[PATCH] PowerPC eabi.asm 64-bit support

[David Edelsohn <dje at watson dot ibm dot com>]

	64-bit PowerPC needs the FPR save and restore helper functions.
It seems most convenient to place them in eabi.asm along with the 32-bit
definitions given that t-ppccomm already has the infrastructure to insert
it properly in libgcc.a.

	Any objections to the following patch?

Thanks, David
