[OE-core] [PATCH 1/1] gcc-sanitizers: Fix libtool library files

[Yuanjie Huang]

From: Yuanjie Huang <yuanjie.huang at windriver.com>

Since libtool sysroot is not set when compiling sanitizers, the libtool
does no prefix the dependency path correctly. Fix it, so that programs
can link to sanitizer libraries without error.

This patch changes the depenedency_libs line in libasan.la and
libusan.la from
	dependency_libs=' -lpthread -ldl '/usr/lib'/libstdc++.la '/usr/lib'/libstdc++.la'
to
	dependency_libs=' -lpthread -ldl =/usr/lib/libstdc++.la =/usr/lib/libstdc++.la'

Upstream-Status: Inappropriate [embedded specific]
(LOCAL REV; NOT UPSTREAM) -- sent to oe-core on 2016-09-20
