Summary: AdjustorAsm.S doesn't build on AIX

Initial Comment:
OK, this is a weird one.

I'm building GHC 6.4.1 on AIX and using IBM's
assembler, since GNU binutils is known to have issues
on AIX.

When the build reached AdjustorAsm.S, I got:

imer.h -#include ProfHeap.h -#include LdvProfile.h
-#include Profiling.h -#inclu
de Apply.h -fvia-C -dcmm-lint     -c AdjustorAsm.S -o
AdjustorAsm.o
Assembler:
/tmp//ccq7dlbU.s: line 15: 1252-016 The specified
opcode or pseudo-op is not val
id.
        Use supported instructions or pseudo-ops only.
/tmp//ccq7dlbU.s: line 48: 1252-149 Instruction subf is

urrent assembly mode COM.

make[2]: *** [AdjustorAsm.o] Error 1

After some research, I added -opta -Wa,-mppc, which
reduced the errors to:

/tmp//ccA1yNhC.s: line 15: 1252-016 The specified
opcode or pseudo-op is not val
id.
        Use supported instructions or pseudo-ops only.
/tmp//ccA1yNhC.s: line 52: 1252-142 Syntax error.
/tmp//ccA1yNhC.s: line 53: 1252-142 Syntax error.
/tmp//ccA1yNhC.s: line 58: 1252-142 Syntax error.
/tmp//ccA1yNhC.s: line 59: 1252-142 Syntax error.

I examined the temp files and found that line 15
contains only the word ".text".

I was finally able to work around the problem by adding
-opta -save-temps to the command line, then using GNU
as like so:

as mppc -I.  AdjustorAsm.s -o AdjustorAsm.o

I then copied the resulting .o file to the thr, p,
debug, etc. .o files.  The build was then able to complete.
