I am not the author of this check, I simply took it from config.guess
https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob;f=config.guess;h=256083a70d35921d544b15f4f51749af89d18b89;hb=HEAD
(Ctrl+F musl)
However, I was the one who requested the musl detection in config.guess
and the maintainer implemented the check like this for reasons of
portability.
Perhaps the problem is the else case in this statement. Maybe it should be:
LIBC="glibc"
if command -v ldd >/dev/null && ldd --version 2>&1 | grep -q ^musl
then
LIBC="musl"
