glib-2.0: drop add-march-i486-into-CFLAGS-automatically.patch

The reasoning behind this patch isn't clear. ${CC} should always
contain appropriate -march flags. If the build is misconfigured
somehow (or someone is trying to build for i386) then we want the
configure scipt to generate an error, not to try to quietly try to
fix it (adding -march=i486 to CFLAGS is potentially going to cause
more problems than it solves).

Since this patch is unlikely to ever be merged upstream and it's not
helpful in any typical OE build, drop it rather than maintaining it.

-Subject: [PATCH] add -march=i486 into CFLAGS automatically
-
-Upstream-Status: Inappropriate [configuration]
-
-glib configure will check if current gcc need -march=i486,
-when gcc need -march=i486 but CFLAGS don't have,
-glib configure will abort and advise the user to add -march=i486 or later.
-This will break the build process,it's not good for automatic build system.
-so change this to adding -march=i485 automatically when it is needed.
