Hello,
For static RTPs, libc_internal is included
in link closures through LIB_SPEC and LIBGCC_SPEC, which makes
it hard to conditionally remove with command line options
such as -nolibc.
This change arranges to have libc_internal dragged in from
LIB_SPEC only and reworks the ordering of libs that
participate in LIB_SPEC to match a rationale that the head
comment can state.
We have been using this for a while in our gcc-7 based toolchains
on several targets.
I checked on a gcc-8 based source tree that I can still
build functional compilers passing Ada ACATS for VxWorks
6.9 and 7.0.
Bootstrapped and reg tested on mainline for x86_64-linux.
With Kind Regards,
Olivier

* config/vxworks.h (VXWORKS_LIBGCC_SPEC): Remove -lc_internal.
Merge block comment with the one ahead of VXWORKS_LIBS_RTP. Then:
(VXWORKS_LIBS_RTP): Minor reordering.
