Indeed. Enabling on musl was solely based on the fact that musl has
support for $ORIGIN since version 0.9.13:

0.9.13 release notes

new features:
- iconv support for EUC-KR and Big5 (including HKSCS) encodings
- field widths (POSIX 2008 feature) in strftime
- recursive rpath and $ORIGIN support in dynamic linker
[...]

What the patch means is that there is a priori no reason to have samba4
depend on uclibc-ng || glibc due to $ORIGIN support: now all of glibc,
uclibc and musl have this functionality.

Best regards,

Thomas
