g++.dg/opt/crossjump1.C: Use { target fpic } when option -fpic or -fPIC

[Hans-Peter Nilsson]

Pretty please everybody, gate -fpic/-fPIC usage on "target fpic"
henceforth as below.  It's not used everywhere, but that's just
because it's relatively recent.  Noticed to fail on
cris-axis-elf and mmix-knuth-mmixware.  Doesn't fail on
cris-axis-linux-gnu with or without this patch.  Committed.

	* g++.dg/opt/crossjump1.C: Gate -fPIC usage on target fpic.
