[PATCH] testsuite: altivec-abi.exp: remove obsolete parameter

[Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com>]

Hi,

the current version of gdb.arch/altivec-abi.exp is crashing on ppc64 with
the following:

Running ../../../gdb.git/gdb/testsuite/gdb.arch/altivec-abi.exp ...
ERROR: tcl error sourcing ../../../gdb.git/gdb/testsuite/gdb.arch/altivec-abi.exp.

"uplevel #0 source ../../../gdb.git/gdb/testsuite/gdb.arch/altivec-abi.exp"

The patch below fixes this issue removing the no longer used parameter 'prefix'
from altivec_abi_tests.

Thanks,
