testsuite: Fix up pr25376.c on powerpc64-linux and array-quals-1.c on powerpc-linux...

The following patch fixes the pr25376.c testcase on powerpc64-linux
and array-quals-1.c on powerpc-linux.
Previously it failed like:

FAIL: gcc.dg/pr25376.c scan-assembler-symbol-section symbol simple\$ (found simple) has section ^\\\\.?my_named_section|simple\\\\[DS\\\\]|^\\\\"\\\\.opd\\\\" (found .opd)

The problem with pr25376.c testcase are the ELFv1 function descriptors,
        .section        my_named_section,"ax",@progbits
        .align 2
        .globl simple
        .section        ".opd","aw"
        .align 3
simple:
        .quad   .L.simple,.TOC.@tocbase,0
        .previous
        .type   simple, @function
.L.simple:

so the simple symbol is found in the .opd section rather than in the
my_named_section the test attempts to verify for that symbol.
This patch deals it with two changes, the last two hunks in scanasm.exp
teach it about the behavior of .previous directive and the first hunk
for powerpc if symbol is in .opd section will try section in which the
.L.symbol label is instead.

The array-quals-1.c test fails because on powerpc-linux the symbols
are emitted into .sdata section rather than one of the expected ones.

	PR testsuite/98325
	* lib/scanasm.exp (dg-scan-symbol-section): For powerpc*-*-* targets if
	$section is .opd, look at .L.$symbol_name's section.
	(parse_section_section_of_symbols): Handle .previous directive.
	* gcc.dg/array-quals-1.c: Allow .sdata section.
