Issue Description:

This test failed for me on Linux:

lukeh@ubuntu:~/CVSRoot/apple$ env SDKROOT= '/home/lukeh/CVSRoot/apple/build/Ninja-DebugAssert/swift-linux-x86_64/bin/swift' -module-cache-path '/tmp/swift-testsuite-clang-module-cacheUl1Ux1' -target x86_64-unknown-gnu-linux -L/foo/ -driver-use-frontend-path /home/lukeh/CVSRoot/apple/swift/test/Driver/Inputs/print-var.sh /home/lukeh/CVSRoot/apple/swift/test/Driver/environment.swift LD_LIBRARY_PATH | /home/lukeh/CVSRoot/apple/build/Ninja-DebugAssert/llvm-linux-x86_64/bin/FileCheck /home/lukeh/CVSRoot/apple/swift/test/Driver/environment.swift

It turns out that I already had LD_LIBRARY_PATH set to point to the build directory (for testing other things in-place), and this seems to have broken the test result. Unsetting LD_LIBRARY_PATH unbreaks the test.

Hm. lit is supposed to filter out potentially hazardous environment variables, and I figured this would be one of them. But we can certainly change the test to explicitly clear LD_LIBRARY_PATH.

Has this been resolved? If so, it should be closed.
