on some targets, the logic for the compiler option -static seems not
to be processed when -pie is present. rather than playing
whack-a-mole, just ensure LD_PIE_SPEC specs always pass -static to ld
if either -static or -static-pie is present on the compiler driver
command line.
this may produce redundant -static arguments but it doesn't matter.
these were added when arm fdpic support was upstreamed in gcc. one patch
was just entirely wrong (broke arm init/fini arrays, gcc pr#114158) and
the other put arm-specific unwind logic in place for all fdpic targets
and broke building of the unwinder code.
this directory uses relative pathnames to access libgcc unwind
headers, but with cowpatch, those are relative to the libstdc++-v3
directory in the unpatched tree unless libstdc++-v3 has been
cow-split.
this calls for a general solution at some point, but for now, just add
an explicit dummy patch to trigger cow splitting.
