Our new shiny Rust 1.57.0 toolchain passes basic tests on all platforms, but it fails to build librsvg on non-x86_64 Musl platforms, because libraries need libc.musl-<ARCH>.so.1, but we don't have such file in our current non-x86_64 Musl toolchains:

% julia -e 'using BinaryBuilderBase; BinaryBuilderBase.runshell(Platform("aarch64", "linux"; libc="musl"))'
sandbox:${WORKSPACE} # echo 'int main(){return 0;}' | cc -x c -; readelf -d a.out | grep NEEDED

/opt/x86_64-linux-musl/x86_64-linux-musl/sys-root/usr/lib/libc.so

However the libc.so file has the correct soname (correctly set in the GCC build recipe: [1] and [2]):

sandbox:${WORKSPACE} # readelf -d /opt/aarch64-linux-musl/aarch64-linux-musl/sys-root/usr/lib/libc.so | grep SONAME
 0x000000000000000e (SONAME)             Library soname: [libc.musl-aarch64.so.1]

The log of librsvg shows

I think the solution is to create the symlink

ln -sv libc.so ${sysroot}/urs/lib/libc.musl-$(musl_arch).so.1

after https://github.com/JuliaPackaging/Yggdrasil/blob/beb4ee8102255237abd5c84e5da25651ccc6b00e/0_RootFS/gcc_common.jl#L701. I'm opening the issue as a reminder, before I get to rebuild all Musl GCCs, sigh.

This has been fixed in this package by #192 but we still need to add the symlink directly in the compiler shards, so the we can remove the hot-fix from here.

Side note: I've been trying to craft a simple example to reproduce the error, to no avail. @haampie provided this similar reproducer (create a library with a soname which doesn't exist, trying to link to it fails, reporting an undefined reference error):

cc -c first.c
cc -shared -Wl,-soname,libdifferensoname.so -o libfirst.so first.o
cc -c second.c
cc -shared -Wl,-rpath,/tmp/tmp.YNOMudfZqn -Wl,-soname,libsecond.so -o libsecond.so second.o -L. -lfirst
cc -c third.c
cc -o main -Wl,-rpath,/tmp/tmp.YNOMudfZqn third.o -L. -lsecond
/usr/bin/ld: warning: libdifferensoname.so, needed by ./libsecond.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: ./libsecond.so: undefined reference to `first'
collect2: error: ld returned 1 exit status
make: *** [Makefile:19: main] Error 1

However I tried to adapt to our case (any simple C program would link to a non-existing libc) but couldn't make the linker fail 😕
