Adding -W,l:$PATH_TO_JUST_COMPILED/libc.a seems to work. The linker than finds __stach_chk_guard for the .so's that require -static-libgcc. This hack is now attached to Bug 726495. A scratch build is also running, in a local mock it was successful: - http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=151594 I'm really not sure how the linker is supposed to find libc.a (which was compiled a little earlier during the building of the glibc package). It works for other architectures, so there must be some trick somewhere... (Note, this is all for F-14's glibc-2.13 on armv5tel.)
