[x264-devel] Fix linker test for -Bsymbolic

[Sean McGovern]

x264 | branch: master | Sean McGovern <gseanmcg at gmail.com> | Mon Oct 17 12:44:03 2011 -0700| [a0ce295b33a1ba87f732e661e22dba1a307e3405] | committer: Jason Garrett-Glaser

Fix linker test for -Bsymbolic
The Solaris linker only accepts -Bsymbolic for objects compiled in dynamic mode (i.e. shared objects), so pass -shared to gcc.
Additionally, for x86_32 unresolved textrels cause a linker error so mark the .text section as 'impure'.
