Hi,

You are right that gnulib should care about cross-compilation to
musl systems. Reason: It's one of the main options when using
'buildroot', see
https://buildroot.org/downloads/manual/manual.html#_cross_compilation_toolchain
(Btw, I like buildroot: it allowed me to create a self-hosting riscv32
environment, while I couldn't find a working VM image for download.)
But several things are suboptimal with your patch:
- You cannot just assume that musl libc works like glibc. These
implementations have no code in common.
- Case clauses like
| *musl* | musl* | *musl
are redundant.
- The starting point must be to determine the "$host_os" value. It is
'linux-musl', but one should be prepared to see version numbers in
there, such as linux5.0-musl1.0.
- It's best to handle all modules at once, not just one.
Create a testdir with the relevant modules (all modules that
contain a .m4 files that has an AC_RUN_IFELSE invocation), and run
this testdir on a system which has a musl libc. I'm using an
Alpine Linux 3.7 system for this purpose.
I'm committing this patch as the result.
