[PATCH v2] bjam-native: do not search all PATHs variable

[<mingli.yu@windriver.com>]

From: Li Wang <li.wang@windriver.com>

By default, it searches all paths specified by $PATH.

But if the directory of the $PATH variable on
build host includes nfs(build host as nfs client),
it causes the build hung when the nfs server is
unavailable.
