Subject: LTO: Specify the use of gold with a compiler option rather than an explicit path
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=b94ab2923c2f1671b628c0210fa8ddc7abe8c617;p=people%2Fandrewcoop%2Fxen-test-framework.git

LTO: Specify the use of gold with a compiler option rather than an explicit path

This allows the compiler to pick up gold from the path, rather than forcing
the use of the system gold all the time.
