Issue: sys-boot/grub-2.06-r6 has implicit function declarations in configure logs (MUSL-CLANG-SYSTEM).
Discovered on: amd64 (internal ref: tinderbox_musl)

NOTE:
(MUSL-CLANG-SYSTEM) in the summary means that bug was found on a machine that runs MUSL libc + clang16 but this bug MAY or MAY NOT BE related to musl/clang16.

This is failing on regex functions that glibc provides but musl does not. If the functions are missing from libc, a replacement from gnulib is used.
