re PR c/43553 (libgcc built with -DHAVE_CC_TLS against xgcc when emutls in use)
2010-03-30 Jack Howarth <howarth@bromo.med.uc.edu>
PR c/43553
* Makefile.in (INTERNAL_CFLAGS): Add @set_use_emutls@.
* configure.ac: Use GCC_CHECK_EMUTLS to see if emulated TLS
is used and substitute set_use_emutls.
* configure: Regenerated.
