gas macro handling broken in 2.16.91.0.1

[Olaf Hering]

I get syntax errors with current mainline cvs, this worked with
binutils-2.16.90.0.3 

example from rpm4:

as --gdwarf2 -a32 -K PIC -mppc -many -V -Qy -o test.o test.s
GNU assembler version 2.16.91.0.1 (powerpc-suse-linux) using BFD version 2.16.91.0.1 20050622 (SuSE Linux)
test.s: Assembler messages:
test.s:99: Error: bad expression
test.s:99: Error: syntax error; found `
