mipsel-linux-musl: error: 'EX_IOERR' was not declared in this scope

Hi there, I got the following error when bootstrapping for a mipsel-linux-musl target on a macOS 10.14 host.

Here is some system information you may find helpful

$ zig version
0.8.0
$ zig env
{
 "zig_exe": "/opt/local/bin/zig",
 "lib_dir": "/opt/local/lib/zig",
 "std_dir": "/opt/local/lib/zig/std",
 "global_cache_dir": "/Users/nalzok/.cache/zig",
 "version": "0.8.0"
}
$ zig libc
Zig attempted to find the path to native system libc headers by executing this command:
zig cc -target mips64-linux-musl -E -Wp,-v -xc /dev/null
error: unable to detect native libc: UnableToSpawnCCompiler

Could you please take a look?
