Trying to build a cross-compiler for build == host == x86_64-linux-musl (Alpine
Linux 3.15) and target == aarch64-apple-darwin leads to the following build
error:
[12:57:48] libtool: compile: x86_64-linux-musl-g++ -DHAVE_CONFIG_H -I.

This was reported on the Iain Sandoe's GCC branch, but appears to be generic
(i.e., not specific to aarch64 at all). It seems like it's an issue with musl
headers, and there has been a similar issue reported in libgccjit before, at
gentoo: https://bugs.gentoo.org/828580 (for which Alpine is shipping a patch:
