[patch] Add dg-require-effective-target fpic to gcc.target/powerpc tests

[Olivier Hainque]

Hello,

This change is a proposal to add 

 /* { dg-require-effective-target fpic } */

to a few tests in gcc.target/powerpc that do use
-fpic or -fPIC but don't currently query the target
support.

This corresponds to what many other fpic tests do
and helps the vxWorks ports at least, as -fpic is
typically not supported in at least one of the two
major modes of such port (kernel vs RTP).

Ok to commit?

Thanks in advance!

Best regards,

Olivier
