[tmk] Improvements for TMK builds on Windows platform

[dxdc]

Improvements for tmk utilities are needed for more general Windows support:

• Add support for all Makefile functionality (tests, clean, etc.)
• Handle BOM or CRLF line endings, e.g., if haystack.txt files are supplied or piped via stdin from Powershell
• Address problems with absolute file paths (e.g., ffmpeg.exe)
• More general solution for missing POSIX getline function on Windows. This can only be compiled currently using some Windows versions of g++ that have getline support (e.g., 32-bit MinGW). The 32-bit version memory limitations restrict the number of files that can be analyzed, however.
