+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:
+
+http://git.savannah.gnu.org/cgit/make.git/tree/glob/glob.c?id=5d653b535a0e0e607c8be2016bcaadd6f326a698#n1333
+
+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.
