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

[Corinna Vinschen <vinschen@redhat.com>]

Hi,

the gdb.arch/i386-unwind.c testcase doesn't compile on Cygwin due to
the missing underscores, the same as with i386-prologue.c.

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