where temporary files are written

[Marty Leisner]

I didn't see an option to tell gcc where to write temporary files
(in currently writes them in in the current directory).

The way linux builds kernel modules is it runs gcc from the KERNEL
install directory, so doing something like

make CC='gcc -save-temps'

writes the temporary files into the kernel directory...(which may be readonly).

What I'm looking to accomplish is

make CC="gcc -save-temps --temppath=$PWD"

to write temporary files into "temppath".

comments?
