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.
