I don't see --gstabs in my version of the gas documentation, but I'll
take your word for it :-)

Appending -Wa,--gstabs to CYGBLD_GLOBAL_CFLAGS might do the trick,
although it may also have side effects on other files. The build
system right now does not really have any special options just for
assembler files because there are so few of them.
