All the tests are designed for a little-endian ARC system. Thus,
update the arc predicate in arc.exp, improve the matching pattern for
linker relaxation test, and add linker scripts to nps-1x tests.
Signed-off-by: Claudiu Zissulescu <claziss@synopsys.com>
Revert "Prevent the ASCII linker script directive from generating huge amounts of padding if the size expression is not a constant."
This reverts commit adbe951fc9.
Revert "ld test asciz and ascii fails"
This reverts the ascii.d part of commit 5f497256be.
Revert "Add support for the ASCII directive inside linker scripts."
This mostly reverts commit 9fe129a410
leaving the asciz.d and asciz.t changes in place.
--relax enables all relaxations. --no-relax-gp disables GP relaxation to
allow measuring its effect.
The option can test effectiveness of GP relaxation and support some ABI
variants that use GP for other purposes.

As discussed in PR ld/29411, the ld warning
[...] has a LOAD segment with RWX permissions
needs to be disabled on all SPARC targets, not just Solaris/SPARC: the
.plt section is required to be RWX by the 32-bit SPARC ELF psABI and the
64-bit SPARC Compliance Definition 2.4.1. Given that ld only supports
SPARC ELF targets, this patch implements this.
Tested on sparc64-unknown-linux-gnu and sparc-sun-solaris2.11.
