Part of the VxWorks 7 configuration specificities is triggered by this piece in libgcc/config.host:
# Common parts for widely ported systems.
case ${host} in
...
*-*-vxworks7)
tmake_file=t-vxworks7
;;
For the powerpc family of targets, this should apply to SPE targets as well.
However, these are typically canonicalized as *-vxworks7spe and the case filter
above fails to match that.
This causes a build failure of libgcc when configured for e500v2-wrs-vxworks,
complaining that semLib.h could not be found while compiling vxlib-tls.c,
despite VSB_DIR being set and the sequence of -I that should allow finding it
in t-vxworks7.
Indeed, we mistakenly use t-vxworks instead of t-vxworks7, and the former
relies on a different environment variable to locate the header files (as
expected for versions of VxWorks prior to 7).
The attached patch fixes this by adding a wildcard after vxworks7 in the
case filter quoted above.
Committing to mainline, after checking that it has the intended effect and
lets the build proceed further.
