musl 1.1.19 introduced the _DIRENT_HAVE_D_* macros in commit
1bc10ffeaa7c7ce44b3e214e02e302642511c7c7, triggering a bug in GNU make
that's present up to the current version:


The glob replacement they ship includes and uses internally a
GLOB_ONLYDIR flag, which is opportunistic and implemented via d_type
if _DIRENT_HAVE_D_TYPE is defined, and it fails to consider that
DT_LNK could be a symlink to a directory. This is an ancient version
of glob.c; the modern GNU glob in glibc rightly considers DT_LNK. Thus
the bug is not seen on glibc systems (where the glob replacement is
not used), but will be seen on any system where _DIRENT_HAVE_D_TYPE is
defined and where configure decides to replace the libc glob with
their GNU one.
