Introduce an internal API for VxWorks version checks
This changes introduces an internal API for VxWorks version checks
within runtime files, a prerequisite to a few fixes coming up for libstdc++
builds on more recent versions of the OS.

gcc/
* config/vxworks/_vxworks-versions.h: New file.
* config.gcc (*-*-vxworks*): Add it to extra_headers.
libgcc/
* config/gthr-vxworks.h: Use _vxworks-versions.h.
* config/gthr-vxworks-tls.c: Likewise.
