------- Comment #2 from joel at gcc dot gnu dot org 2009-08-18 13:28 ------- If you need CFLAGS_FOR_TARGET set to find the files or specify target specific compiler options required to compile the run-time, then yes.
This certainly breaks any cross build that is non-multilib and specifies target specific CPU model CFLAGS. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41096
