[build] Add --divide to ASFLAGS if supported by the assembler
Some builds of the GNU assembler will treat a '/' character as a
comment delimiter. Adding "--divide" will cause it to be treated as a
division operator, as we expect. The "--divide" option is not
available in all gas versions, so apply it only conditionally.
