I am in fact using version 1.1.19 and don't have the option to upgrade to 1.1.20. My config.mak file also contains the option -Bsymbolic-functions in the LDFLAGS_AUTO variable.

It's almost certainly a matter of using a pre-1.1.20 version of musl,
or having an old config.mak from pre-1.1.20 musl (with
-Bsymbolic-functions) rather than re-running configure with the
current version.
