[PATCH] ld/arc: Fix linker for big-endian arc targets

[PATCH] ld/arc: Fix linker for big-endian arc targets

[Andrew Burgess]

This aims to bring the linker for big-endian arc targets into line with
the linker for (the default) little endian arc targets.

The bulk of the changes are to extend the target pattern in the test
files from 'arc-*...' to 'arc*-*...' and so match both big and little
endian arc targets.

In the ld/emulparams/ directory the existing scripts checked for a
variable ARC_ENDIAN to switch between big and little endian targets,
however, this variable is never set up.

So, a new script snippet is introduced which sets up ARC_ENDIAN based on
the value of target, this snippet is then included from all of the
existing arc scripts.

The existing big-endian variants of all the scripts, which existed, but
were never used, are deleted in this commit.

Subject: [PATCH] ld/arc: Fix linker for big-endian arc targets

This aims to bring the linker for big-endian arc targets into line with
the linker for (the default) little endian arc targets.

The bulk of the changes are to extend the target pattern in the test
files from 'arc-*...' to 'arc*-*...' and so match both big and little
endian arc targets.

In the ld/emulparams/ directory the existing scripts checked for a
variable ARC_ENDIAN to switch between big and little endian targets,
however, this variable is never set up.

So, a new script snippet is introduced which sets up ARC_ENDIAN based on
the value of target, this snippet is then included from all of the
existing arc scripts.

The existing big-endian variants of all the scripts, which existed, but
were never used, are deleted in this commit.

Indeed the Andrew's patch breaks the build.  Attached my solution for the problem. 

Ok to commit?

Sorry about that, the patch below should fix things.  OK to apply?

ld/arc: Make little endian default choice for linker scripts

When building with --enable-targets=all the target string is not set to
something that matches the pattern arc*-*, and so the script used to
decide if we should build big or little endian linker script currently
exits with an error.

This commit makes little endian linker script be the default, which will
be used when building for all targets, this matches the behaviour from
before I made the endianness switchable, when we only ever built little
endian linker scripts anyway.

Andrew,

Probably it is ok to commit it as it may break builds for other people, and the solution is very simple.

Best,

Pushed as an "obvious" fix.  If there's disagreement later it can be
backed out.
