Summary:
When running the compiler-rt testsuite on FreeBSD (it didn't matter which version), I always got the same error result:
FAILED: cd /home/dim/obj/llvm-234092-trunk-freebsd10-amd64-ninja-rel-1/projects/compiler-rt/lib && LLVM_CHECKOUT=/home/dim/src/llvm/trunk SILENT=1 TMPDIR= PYTHON_EXECUTABLE=/usr/local/bin/python2.7 COMPILER_RT=/home/dim/src/llvm/trunk/projects/compiler-rt /home/dim/src/llvm/trunk/projects/compiler-rt/lib/sanitizer_common/scripts/check_lint.sh
The following differences between the implemented custom wrappers and the tests have been found:

After some investigation, it turns out to be due to the regex used for search test_ symbols in lib/dfsan/scripts/check_customer_wrappers.sh:
grep -E "^\\s*test_.*\(\);" ${DFSAN_CUSTOM_TESTS}
This uses \s to search for whitespace at start of line, but support for \s was only introduced in GNU grep v2.5.4-112-gf979ca0, while both FreeBSD and OSX only have grep 2.5.1 (the last version released under GPLv2).
I propose to change \s into [[:space:]], which is the more portable notation.
Test Plan: Run regression tests, and see that they work now. :)

On a default FreeBSD install Bash is not installed and fdescfs is not
mounted. Use plain sh functionality instead.

- Introduce several new custom glibc wrappers
- Implement some of the not yet implemented wrappers
- Refactor and extend the tests
- Add script to make sure all declare custom glibc wrappers are implemented & tested.
