on opt_global.h. This actually matters for genassym.o (it depends
on at least SMP).
Don't undefine KERNEL for compiling genassym.c. genassym.o really
depends on KERNEL, and the prototype mismatches that required
undefining KERNEL in rev.1.49 no longer exist.
Compile gensetdefs* with the same flags as genassym*. External
`gen' programs such linux_genassym should also use these flags
(${GEN_CFLAGS}).
Fixed missing dependency generation for gensetdefs.o. C sources
for external `gen' programs should be added to GEN_CFILES to get
their dependencies generated.
Cleaned up flags definitions and use. All of ${CFLAGS} is now
passed to mkdep and the assembler (both are actually variants of
${CC} and will ignore the irrelevant flags).
