aic7xxx: aicasm correct include file

aicasm just puts the value of the "-i" passed include file in the
generated file with quotes around it. This means that there are manual
edits made to aic7xxx_reg_print.c and aic79xx_reg_print.c

now we check to see if the value passed to '-i' starts with a '<', if it
does don't output the quotes.

Re-support CWARNFLAGS, lost when bsd.sys.mk was removed. Also, support
CWARNFALGS.$file centrally so we don't have to have it in all the
places. Remove a few warning flags that are no longer needed.
Also, always use -Wno-unknown-pragma to (hopefully temporarily) work
around #pragma ident in debug.h in the opensolaris code. Remove some
stale warning suppression that's no longer necessary.

Re-enable -Werror for these modules. It is already enabled for the same
files when built as part of a kernel.

Remove aicasm as a build dependency. It made sense when the ahc and ahd
drivers and their firmware were under active development, but those days
have passed. The firmware now exists in pre-compiled form, no longer
dependent on it's sources or on aicasm. If you wish to rebuild the
firmware from source, the glue still exists under the 'make firmware'
target in sys/modules/aic7xxx.

This also fixes the problem introduced with r257777 et al with building
kernels the old fashioned way in sys/$arch/compile/$CONFIG when the
ahc/ahd drivers were included.

Rework the aicasm build machinery so that it gets built along with toolchain
components instead of with the kernel and/or modules. This ensures that it
gets built with the host compiler, not the compiler in obj/... used to build
the target components (which may be a cross-compiler outputting code for a
different architecture and using header files with types and options set up
for the wrong architecture).

Hook the aic7xxx modules up. This requires some extra care since aicasm
is a compiler tool and needs to be compiled by the host compiler. I've
tested this in i386->sparc cross-build, 4.7->current upgrade, normal
buildkernel target, and normal /sys/i386/compile/GENERIC configurations.
