[FFmpeg-devel] gcc -rdynamic flag not supported, yet configure keeps propogating

[Ben Taylor]

Solaris 10/X86, gcc-3.4.3.   I'm running basic configuration tests
with some patches to configure for Solaris, and I see this check
for "-rdynamic" fail (gcc emits "gcc: unrecognized option `-rdynamic')
The log is below.

Running the tests manually, it appears that the binary gets created
as expected, but gcc emits that "warning" and doesn't return a non-zero
value.

Should the check for -rdyanmic look for something like that warning
and disable it if found?

Thoughts?
