Compiling for arm-linux-gnueabihf with libc linked failed

[ikskuh]

I wanted to cross-compile a project using libc to a arm platform, but it looks like glibc is broken, it fails with the following error message:

error(compilation): clang failed with stderr: In file included from ./zig-linux-x86_64-0.9.0-dev.771+493822ac3/lib/zig/libc/glibc/sysdeps/arm/crti.S:44:

The file compiled to produce this error is this:

pub fn main() void { }

The error happens when compiling with the following commands:

zig build-exe -lc test.zig -target arm-linux-gnueabi
zig build-exe -lc test.zig -target arm-linux-gnueabihf
zig build-exe -lc test.zig -target thumb-linux-gnueabi
zig build-exe -lc test.zig -target thumb-linux-gnueabihf

but not when compiling for musl:

zig build-exe -lc test.zig -target thumb-linux-musleabi
# … didn't try on that specific commit, but worked previously

Is this an already known problem?
