Move the body of GCCInstallationDetector ctor into an init() function and call it from its only user. The linux toolchain. This saves quite a lot of directory searching on other platforms. See http://docs.freebsd.org/cgi/mid.cgi?51E6FAF5.3080802 for the original discussion. With this fix, the search for gcc installations is completely eliminated on FreeBSD.
