[RFA] testsuite/gdb.arch/i386-prologue.c: Fix compiling on Cygwin

[Corinna Vinschen <vinschen@redhat.com>]

Hi,

the gdb.arch/i386-prologue.c testcase doesn't compile on Cygwin since
on Cygwin the assenmbler labels need leading underscores to match the
same names in C.  The below patch fixes that.

	* gdb.arch/i386-prologue.c: Conditionalize label names to build
	on Cygwin.
