[PATCH] [vxworks] avoid mangling __STDC_VERSION_LIMITS_H__

[Alexandre Oliva <oliva@adacore.com>]

The mangling of the macro name that guards limits.h from reinclusion
was mangling a c23-required macro as well.  Make the edit pattern
stricter.

Regstrapped on x86_64-linux-gnu.  Also tested with gcc-13 on arm-,
aarch64-, x86- and x86_64-vxworks7r2.  Ok to install?

	* config/t-vxworks (vxw-glimits.h): Don't mangle c23-required
	__STDC_VERSION_LIMITS_H__ define.

More tolerance and less prejudice are key for inclusion and diversity
Excluding neuro-others for not behaving ""normal"" is *not* inclusive
