[PATCH 2/6] x86: also allow %st(N) in CFI directives

[Jan Beulich]

In 0e0eea782025 ("x86: x87-related adjustments") I screwed up CFI
directives with FPU support disabled, by moving the conditional there
across a check of "allow_pseudo_reg". Add the missing check.

	* config/tc-i386.c (parse_real_register): Add allow_pseudo_reg
	check to %st(N) parsing logic.
	* testsuite/gas/cfi/cfi-i386.s: Set "generic32" arch.
