testsuite: Allow .sdata in more cases in gcc.dg/array-quals-1.c

testsuite: Allow .sdata in more cases in gcc.dg/array-quals-1.c

[Joseph Myers]

When testing for Nios II (gcc-testresults shows this for MIPS as
well), failures of gcc.dg/array-quals-1.c appear where a symbol was
found in .sdata rather than one of the expected sections.

FAIL: gcc.dg/array-quals-1.c scan-assembler-symbol-section symbol ^_?a$ (found a) has section ^\\.(const|rodata|srodata)|\\[RO\\] (found .sdata)
FAIL: gcc.dg/array-quals-1.c scan-assembler-symbol-section symbol ^_?b$ (found b) has section ^\\.(const|rodata|srodata)|\\[RO\\] (found .sdata)
FAIL: gcc.dg/array-quals-1.c scan-assembler-symbol-section symbol ^_?c$ (found c) has section ^\\.(const|rodata|srodata)|\\[RO\\] (found .sdata)
FAIL: gcc.dg/array-quals-1.c scan-assembler-symbol-section symbol ^_?d$ (found d) has section ^\\.(const|rodata|srodata)|\\[RO\\] (found .sdata)

Jakub's commit 0b34dbc0a24864b1674bff7a92fa3cf0f1cbcea1 allowed .sdata
for many variables in that test where use of .sdata caused a failure
on powerpc-linux.  I'm presuming the choice of which variables had
.sdata allowed was based only on the code generated for powerpc-linux,
not on any reason it would be wrong to allow it for the other
variables; thus, this patch adjusts the test to allow .sdata for some
more variables where that is needed on Nios II (and in one case where
it's not needed on Nios II, but the test results on gcc-testresults
suggest that it is needed on MIPS).

Tested with no regressions with cross to nios2-elf.  OK to commit?

	* gcc.dg/array-quals-1.c: Allow .sdata section in more cases.
