Fix the build failure when built with newer gcc:
/home/pmos/build/src/gcc-6.4.0/gcc/config/i386/i386.c: In function 'int function_arg_advance_32(CUMULATIVE_ARGS*, machine_mode, const_tree, long int, long int)':

Fix the following error:
gcc/graphite-isl-ast-to-gimple.c:114:7: error: 'isl_id_free' was not declared in this scope; did you mean 'isl_aff_free'?
Found the patch here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86724
Note that Alpine edge has isl 0.18 and not 0.20, but the error message
is the same and the patch works.
[ci:skip-vercheck]: no need to rebuild existing packages for this

Rebuild all other GCC packages against mpfr4, so they don't fail with:
Error loading shared library libmpfr.so.4: No such file or directory (needed by /usr/gcc4/libexec/gcc/x86_64-alpine-linux-musl/4.9.2/cc1)
[ci:skip-build]: won't finish in time
Related: 2b32ed3a48786fa151cad8f920e5d9997bee94ed in Alpine's aports.git
Explicitly depend on mpc1. Our generated gcc aports use the !tracedeps
option, so we need to explicitly set the libraries it depends on.
This has mostly not been an issue, as we are installing our gcc
packages together with Alpine's gcc package, which causes the libraries
to get installed anyway.
Fixes#236.
[ci:skip-build]: takes too long to build.
I thought only having specific symlinks was enough, and it was for one
kernel. However, to make sure it works with all kernels, let's just add
symlinks for all the binutils.
* remove everything that causes conflicts when installing gcc6 and
gcc6-armhf side by side
* fix up the existing "if cross compiling" code path to use the
/usr/gcc6 prefix
* link binutils binaries to the locations they are expected to be
by gcc (this took me hours to figure out....) as well as by the
linux build system with CROSS_COMPILE
* link all gcc binaries to /usr/bin/gcc6-*
Based on the last version from Alpine, but installed to /usr/gcc6 and
with pretty much everything disabled except for the C compiler.
We can probably throw out a lot of patches, and make the APKBUILD much
smaller. But let's focus on making it possible to compile old kernels
again first. There's still a lot to do for that, see #103.
