PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount. Remove all references to PLATFORM_LINUX and compile match_fstype.c if mount or umount is enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
