+The sed expression is wrong, any flags with '-g' in any position gets
+zapped, for example:
+
+-mfloat-gprs=double (for powerpc e500) -> -mfloatprs=double.
+
+Which gives build errors and is perfectly valid in real use scenarios to
+switch from e500v1 (single precision) code to e500v2 (double precision) code.

Add patch to avoid the enable/disable-debug options from unsetting -g from CFLAGS in an incorrect way which breaks -mfloat-gprs=X (translit to -mfloatprs=X). It's possible to affect other less common CFLAGS with a '-g' in any position. Upstream status: sent different patch (configure.ac) - to avoid autoreconfiguring.
