[PATCH] PPC fix build break caused by VMX instructions

[Steve Munroe]

As recent binutls change requires the user to specifically select a cpu 
type that supports VMX to allow the assembly of VMX instructions. This 
causes the compile of setjmp/__longjmp etc to fail.

The work around passes -many to the assembler for these functions. The 
attached patch adds "-Wa,-many" to CPPFLAGS for the specific functions 
involved.

Its it interesting that the ASFLAGS-setjmp.S form would seem to be more 
appropriate but does not work.
