Daniel Leung 7308fdc3c7 cmake: add --divide to GNU assembler options for x86
GNU Assembler, by default on non-Linux targets, treats slashes as
start of comments on i386.
(https://sourceware.org/binutils/docs-2.33.1/as/i386_002dChars.html#i386_002dChars)
In order to use division, `--divide` needs to be passed to
the assembler.
