[BUG] x86 scratches can have errors due to problematic data being included by objdump

[1superchip]

Some scratches do not work due to extra data objdump emits in its output.
The compiler can generate extra functions/data in a .text$x section which is dumped by objdump if "-j .text" isn't passed.

Error shown in the scratch:
"Diff error: Error running asm-differ: failed to find address immediate for line 'add %al,(%eax)'"
This error is from asm-differ attempting to process incorrect data which is included in the objdump output.

Expected behavior
The problematic data should not be included in the objdump output by passing "-j .text".

Additional context
i686-w64-mingw32-objdump dumps .text and .text$x when it is not passed a section to dump with the -j option.
objdump does not dump .text$x when passed "-j .text".
