MFC r321256:

Include ARCH_FLAGS in CFLAGS when building modules.

Without this change, modules will match the default compiler
configuration which may not be the same as the kernel values.

MFC 299310:
Don't store generated firmware object files in the source directory.

Trim the leading directory of a firmware source file from the resulting
target object file name so the object file is stored in the object
directory. Previously, using 'FIRMWS= /path/to/fw.bin:fw.bin' would
store the generated 'fw.bin.fwo' file in the /path/to directory. Now
it stores it in the object directory of the kernel module being built.

MFH (r293033): ignore unload unless loaded + add a reload target

MFC r276645:

Don't allow clang to use fpu instructions or registers in kernel modules.

MFC r276525, r276596:

Put in a workaround for bug 196407 (arm modules cause crashes & panics).
(Don't allow movw/movt insn in modules.)

Fix alignment directives in arm asm code after clang 3.5 import.

MFC r262733:
Use a full path to the target for make rules which create symlinks @,
machine and ${MACHINE_CPUARCH}. Otherwise the presence of a file named
"x86" or "x86.c" in the make path can cause problems.
