AIX: Update libafs CFLAGS for Open XL C 17.1+
When building the libafs kernel module, we pass various flags to the
compiler and linker, some of which no longer work with the clang-based
Open XL C 17.1 and newer:
On XL C 16.1 and below, the -M argument causes a file to be generated
with a listing of all the files upon which the .o is dependent. This
file is created with the same name as the .o file, but with a .u
extension. With the Open XL C 17.1+ compilers, the -M file acts
similarly, but if -o is specified, the dependency file is created
with the name specified by the -o argument. This causes the
dependency file to be created but not the actual object code file.
Because the compiler invocation succeeds, this repeats until it is
time to link, which fails because the .o files are not actually code,
but ascii files containing the dependency information. We don't
actually use the .u files for anything, so to avoid this issue, remove
the -M flag.
The -H8 flag is a linker argument that aligns the text, data, and loader
sections of the output file so that each section begins on a file offset
that is a multiple of 8. On XL C 16.1 and below, the compiler passes
unrecognized arguments to the linker, and so giving -H8 to the compiler
works fine. But with XL C 17.1+, the compiler does not pass unrecognized
arguments to the linker, and throws an error instead. To avoid this,
move -H8 from KDEFS to LDFLAGS, so it's given only to the linker and not
to the compiler.
The -q64 flag no longer exists with XL C 17.1+, and is replaced by -m64.
Use ${XCFLAGS64} instead of -q64, which will choose the correct flag to
use, like we did in commit aa82a8894f (export: Use XCFLAGS64 for -q64).
