radeon has different case but same name firmware files. the lower case
ones are already installed into /libdata/firmware, and to avoid having
to provide some special method to build on systems with case-preserving
file systems (such as macOS), we install the lower case ones in /usr.
this means that anyone that requires the lower case files must either
have /usr as part of the / file system, or manually keep them updated.
last part of PR#54976, though i doubt we'll try to pull up these.
this is enabled on i386, amd64 and arm64.
./usr/include/$MACHINE and automatically add it.
add sun68k for sun2/sun3. tested on about 12 platforms.
there may be more failures to figure out but this should make
them all special cases rather than always expected cases.
fortunately, most builds don't see to hit these issues for
reasons i haven't determined yet.
put compat stuff in NetBSD.compat.$MACHINE_ARCH, and normal
stuff in NetBSD.dist.$MACHINE/MACHINE_ARCH, etc.
probably need at at more files for sh3, mips, ppc, sparc,
m68k, arm, ia64, etc., as every port has port- or arch-
specific header subdirectory.
./usr/include/dev/nvmm/x86 (amd64).
(perhaps we should stop 'make includes' from creating the target directory
for normal builds as this leads to mtree inconsistencies.)
and the information from compat/archdirs.mk. Also add suport MKCOMPATTESTS
and process the NetBSD.dist.tests to generate appropriate compat directories.
