Subject: ld/testsuite: add support for remote testing in ld-cdtest
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7431e2b766ea7defd2db07c53a39fdd57606b691;p=thirdparty%2Fbinutils-gdb.git

ld/testsuite: add support for remote testing in ld-cdtest

This converts the existing to code to use "remote_load" allowing
execution on both native and remote targets.

The "diff" between the output and the expected result has been
transformed to the usual regexp_diff. The previous could have been
transformed into `remote_exec build diff` but tends to be fickled with
new lines.
