Escapes metacharacters in path component in 'sub search_from'.

Directories with regexp metacharacters in them (like '+') cause some regexp
operation on line 1106 to fail .
Proposed fix attached.

Reproduction recipe:

1) Download QT 4.3.1 (Win32) and unpack. [1]
2) cd to qt-win-opensource-src-4.3.1.
3) Run 'winemaker'.

It'll churn for a while, then you get this message:
Nested quantifiers in regex; marked by <-- HERE in m/^linux-g++ <-- HERE $/ at
/usr/local/bin/winemaker line 1106, <FILEI> line 39.
