arm-wrs-vxworks is the only ARM port to include svr4.h, and its current
ASM_SPEC is based on svr4.h's (with -Q options removed).  This means that
we don't pass things like -mfpu down to the assembler, leading to many
assembler errors from Julian's neon tests.

I thought the best fix would be to make VxWorks work like other ARM
ports, so the patch below removes svr4.h from $tm_file.  I compared the
-dM output for the current configuration with the -dM output you get
when svr4.h is removed, and added the other differences to vxworks.h.

Tested on arm-wrs-vxworks. OK to install?

ok
