unwind-dw2-fde-glibc.c: Define and use USE_PT_GNU_EH_FRAME.
2009-09-22 Loren J. Rittle <ljrittle@acm.org>
* unwind-dw2-fde-glibc.c: Define and use USE_PT_GNU_EH_FRAME.
Enable a new case for __FreeBSD__ >= 7.
* crtstuff.c: Define USE_PT_GNU_EH_FRAME for __FreeBSD__ >= 7.
* config/t-freebsd: Define LIB2ADDEH and LIB2ADDEHDEP.
* config/freebsd-spec.h: Conditionally define LINK_EH_SPEC
and USE_LD_AS_NEEDED.
