recordmount.pl should use the already define environment variables:
$CC + $CFLAGS
$LD + $LDFLAGS
$OBJCOPY, $OBJCOPYFLAGS
$OBJDUMP

We need to set $OBJCOPYFLAFS to a sensible variable in arch/x86/Makefile
And we should introduce $OBJDUMPFLAGS too.

This would solve all the problems - no?

I am limited in time atm - so relying on one of you to create the patch
and do some testing.
