cross/gcc4-{aarch64,armv7}: add generated aports

Make it possible to build old kernels with gcc4 for armv7 and aarch64. The packages have been generated with (as usually): $ pmbootstrap aportgen gcc4-aarch64 gcc4-armv7 [ci:skip-build]: I have tested that this builds locally. Fixes #193.

+When cross compiling a target gcc, target flags may be used on the host
+
+Configure identifies a number of warning flags (WARN_CFLAGS and
+WARN_CXXFLAGS) from the $CC value.  The cross compiler may be different
+from the host compiler and may not support the same set of flags.  This
+leads to problems such as:
+
+cc1plus: error: unrecognized command line option "-Wno-narrowing"
+cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
+
+Work around this problem by removing the warning flags from the
+BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.

+Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
+as otherwise we get link failures if some objects are -fstack-protector built
+and final link happens with -fno-stack-protector. This seems to be the common
+case when bootstrapping gcc, the piepatches do not seem to fully fix the
+crosstoolchain and  bootstrap sequence wrt. stack-protector flag usage.

+
+	* gcc.c (execute): Don't free first string early, but at the end
+	of the function.  Call retry_ice if compiler exited with
+	ICE_EXIT_CODE.
+	(retry_ice): New function.
+	* diagnostic.c (diagnostic_count_diagnostic,
+	diagnostic_action_after_output, error_recursion): Exit with
+	ICE_EXIT_CODE instead of FATAL_EXIT_CODE.

+Subject: [PATCH] Pass unpromoted argument to promote_function_mode
+
+This patch updates setup_incoming_promotions in combine.c to match what
+is actually passed in assign_parm_setup_reg in function.c.
+
+Backported from mainline:
+
+gcc/
+
+	PR rtl-optimization/64037
+	* combine.c (setup_incoming_promotions): Pass the argument
+	before any promotions happen to promote_function_mode.
+
+gcc/testsuite/
+
+	PR rtl-optimization/64037
+	* g++.dg/pr64037.C: New test.
+
+

+When cross compiling a target gcc, target flags may be used on the host
+
+Configure identifies a number of warning flags (WARN_CFLAGS and
+WARN_CXXFLAGS) from the $CC value.  The cross compiler may be different
+from the host compiler and may not support the same set of flags.  This
+leads to problems such as:
+
+cc1plus: error: unrecognized command line option "-Wno-narrowing"
+cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
+
+Work around this problem by removing the warning flags from the
+BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.

+Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
+as otherwise we get link failures if some objects are -fstack-protector built
+and final link happens with -fno-stack-protector. This seems to be the common
+case when bootstrapping gcc, the piepatches do not seem to fully fix the
+crosstoolchain and  bootstrap sequence wrt. stack-protector flag usage.

+	* gcc.c (execute): Don't free first string early, but at the end

+	(retry_ice): New function.
+	* diagnostic.c (diagnostic_count_diagnostic,
+	diagnostic_action_after_output, error_recursion): Exit with
+	ICE_EXIT_CODE instead of FATAL_EXIT_CODE.

+Subject: [PATCH] Pass unpromoted argument to promote_function_mode
+
+This patch updates setup_incoming_promotions in combine.c to match what
+is actually passed in assign_parm_setup_reg in function.c.
+
+Backported from mainline:
+
+gcc/
+
+	PR rtl-optimization/64037
+	* combine.c (setup_incoming_promotions): Pass the argument
+	before any promotions happen to promote_function_mode.
+
+gcc/testsuite/
+
+	PR rtl-optimization/64037
+	* g++.dg/pr64037.C: New test.
+
+
