ld should search search in sysroot first

When ld was configured with a sysroot, it should always search for libraries
with absolute filename in this sysroot first. This patch was tested on
x86_64-pc-linux-gnu without sysroot and armv4tl-softfloat-linux-gnueabi with
sysroot and works ffine on both.
