Subject: testsuite: lto: transform gcc-ar to include prefix
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c9addbc79ac0f9089e69965fec6b386833b3de32;p=thirdparty%2Fgcc.git

testsuite: lto: transform gcc-ar to include prefix

When the the gcc binary is named arm-none-eabi-gcc, the gcc-ar binary
will be named arm-none-eabi-gcc-ar.  The current approach works fine as
long as the binary does not contain any prefix, but if it does, the
gcc-ar binary will not be found.

	* lib/lto.exp (lto-build-archive): Transform gcc-ar binary name.
