You're in luck!  dg-warning and similar directives can be skipped or
xfailed for particular targets, but those don't take options into
account.  There is, however, an effective-target keyword for fpic.

The directives used in the GCC testsuite, along with effective-target
keywords and target/xfail selectors, are documented at
http://gcc.gnu.org/onlinedocs/gccint/Test-Directives.html.

Something like

  { dg-warning "regexp" { "" { target { ! fpic } } } }

If it should only be ignored for fpic for particular targets you
can specify that in the target selector.
