abuild traces shared library dependencies for binaries in built
packages, and adds all of them to depends. This is needed for the cross
gcc builds, as otherwise it will not add the isl dependency (currently
isl25).
With the crossdirect compilation method we mount the cross-gcc from the
native chroot in the foreign arch chroot. Due to the missing dependency,
isl was not installed in the native chroot, and so when attempting to
use that native cross gcc from the foreign arch chroot, it would try to
load the foreign arch isl instead of the native one. Resulting in lots
of the following errors (and of course not a working gcc):
Error relocating /usr/lib/libisl.so.23: unsupported relocation type 1026
I had probably added '!tracedeps' because abuild complains about it
otherwise... but as noted in [1] these complaints are safe to ignore.
Keep !strip for now even though it's not in Alpine's APKBUILD. I've
tried to build without and the build fails with:
strip: Unable to recognise the format of the input file `./usr/aarch64-alpine-linux-musl/lib/libgcc_s.so.1'
