[PATCH v2 1/3] glob: drop needless ifdeffery in {glob,fnmatch}.h

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The implementation of the glob and fnmatch functions is taken from glibc
and it shows in the amount of #ifdefs. We don't need that in barebox and
can even get the glob_t size down by dropping unused members, so let's
do that.
