This is because it is a borrowed file from glibc, and we try to
minimize changes to such a file.

If you need HAVE_STRING_H to force inclusion of <string.h> on your
platform, doing this:

>        COMPAT_CFLAGS += -DHAVE_STRING_H=1 # needed in compat/fnmatch/fnmatch.c

is perfectly the right thing to do.

We try to minimize changes to such a file we borrow from upstream;
especially we do not do so lightly when we have to ask "do platforms
exist?"  Of course, they do---otherwise glibc folks wouldn't have
written such a conditional.
