I guess that is better when configure found gssapi/gssapi.h to search
for gssapi/gssapi_krb5.h and gssapi/gssapi_generic.h
if not to search for gssapi.h gssapi_krb5.h and gssapi_generic.h, but
you patch is more simple.

Opposite of simple patch is proper detection of header files without
extra platform specific flags like "check_gssapi_gssapi_h_first=1".
