[No changes from V3, V2, V1]

Both gdb and sim need buildsystem fixes to now include libctfframe for a
successful build.

gdb/ChangeLog:
	* acinclude.m4: Fix GDB_AC_CHECK_BFD to include libctfframe.
	* Makefile.in: Bring in libctfframe for linking.
	* configure.ac: Check for static or shared.
	* configure: Regenerated.

sim/common/ChangeLog:
	* sim/common/Make-common.in: Bring in libctfframe.a for linking.
