The unconditional assignment performed in t-vxworks to handle include flags currently overrides what specific cpu ports had for the regular (!vxworks) crtstuff objects.
This was not done on purpose and the proposed change adjusts the
configuration bits to apply the vxworks specific flags on top of
the cpu ones instead.
I had good builds and test results with this in-house for gcc-11 based
toolchains for a variety of targets. I checked that a build for vx6.9
passes with mainline sources and verified that the spurious configure
test failures are gone.

* config.host (powerpc*-wrs-vxworks7*): Place t-crtstuff
ahead of the other files in tmake_files.
* config/t-vxworks: Add to CRTSTUFF_T_CFLAGS instead of
overriding it.
