Don't build with !tracedeps, as otherwise the isl dependency is not
properly added to the built gccs. In practice this probably doesn't
matter since we only use these old gccs to build kernels in the native
chroots (not via crossdirect in foreign arch chroots), and we also
install a proper gcc in the native chroot that pulls in the isl
dependency. But fix it for correctness.

Previously only cross/gcc{4,6}-* packages were adjusted in MR 3419, but
these packages need to be adjusted as well.
Fix for error shown in upstream_compat check:
Increase 'gcc6' pkgrel (10 -> 11), missing depend(s): isl
Increase 'gcc4' pkgrel (5 -> 6), missing depend(s): isl

Bump the pkgrel of gcc4 and gcc6, and regenerate the cross/* versions
with "pmbootstrap aportgen gcc6-armv7" etc.
Should fix these errors:

Fix the following error:

Found the patch here:

Note that Alpine edge has isl 0.18 and not 0.20, but the error message
is the same and the patch works.

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.
