gold patch committed: Add -z notext, use it in testsuite

[Ian Lance Taylor]

One of the gold tests fails on Solaris because on Solaris gcc passes -z
text when using -shared.  The GNU linker does not support -z text and
simply ignores it (as is true of all unrecognized -z options).  Gold
does support -z text, which causes it to reject shared libraries with
dynamic relocations in the text segment.  Some of the tests are
specifically testing that that works, and those tests fails.  This patch
adds -z notext, which overrides a -z text appearing earlier on the
command line, and uses it for all tests which might need it.  Committed
to mainline.
