Committed, cleanup of intended users of { target fpic }

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

Yep, the tests are now *all* skipped as not supporting
-fpic/-fPIC, where some had target-specific skips and
inconsistently others were previously compiled but related
error/warning messages were being pruned, incidentally on
targets I maintain.  IMHO skipping the tests follows the
intention better than providing alternative options to compile
*without* -fpic/-fPIC for non- "{ target fpic }" (see
g++.dg/opt/crossjump1.C).

Gets rid of most remaining FAILs for cris-axis-elf.  (Some others
are just malformed tests. :-)

IMO using -fpic / -fPIC should cause an error instead of quietly
emitting non-fpic for targets that don't generate the applicable
"position-independent code", to be linked with -shared.

Committed.
