This commit was manufactured to restore the state of the 8.0-RELEASE image.
MFC Revision 197277:2009-10-20T19:05:43ZAlexander Kabaevkan@FreeBSD.org2009-10-20T19:05:43Zurn:sha1:8ed4544ca7c66155063f4b903356e971620293e1
Make libc.a provide __stack_chk_fail_local weak alias. This is
needed to satisfy static libraries that are compiled with -fpic
and linked into static binary afterwards. Several libraries in
gcc are examples of such static libs.

Second attempt at eliminating .text relocations in shared libraries2009-07-14T21:19:13ZAlexander Kabaevkan@FreeBSD.org2009-07-14T21:19:13Zurn:sha1:2286fe763592aa13d320186bf3e233a560af749b
compiled with stack protector.
Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC
generates local calls to this function which result in absolute
relocations put into position-independent code segment, making dynamic
loader do extra work every time given shared library is being relocated
and making affected text pages non-shareable.
