[PATCH 0/1] MR4013: configure: Fix restoring CFLAGS after the test for -Wl,-z,defs.

[Martin Storsjö (＠mstorsjo)]

This fixes a regression from 450c358881dbc6dcfb2692b8f4debb7db8fdc54b;
after testing for -Wl,-z,defs, CFLAGS was restored from an
incorrect variable, leaving CFLAGS essentially empty.

This would break builds for e.g. arm with Clang, where -mthumb would
be essential for being able to build some inline assembly snippets
correctly.

This also had the effect of dropping the default "-g -O2" arguments
from CFLAGS.

I leave regenerating the configure script up to @julliard - I believe that's the usual procedure for such things.

Thanks, didn't know.
