Subject: [PATCH] python310Packages.gssapi: support cross compilation

`GSSAPI_SUPPORT_DETECT` defaults to true and instructs setup.py to
perform a sanity check before enabling each gss extension. that sanity
check is to `dlopen` the dependency, which fails for cross compilation.

setting `GSSAPI_SUPPORT_DETECT=false` enables all extensions, it simply
bypasses the `dlopen` check.
