If I add some nop into break-asm-file1.s like this,
diff mbox

I get the following error:

gdb/testsuite/gdb.linespec/break-asm-file1.s: Fatal error: duplicate .debug_line sections

break-asm-file0.s and break-asm-file1.s have already had debug information
(written manually), so don't need to generate debug infor for them.

gdb/testsuite:

	* gdb.linespec/break-asm-file.exp: Don't call prepare_for_testing.
	Call gdb_compile instead to compile each .s files without debug
	information.
