scripts: remove . from $PATH
Add CT_SanitizePath function which removes entries referring to ., /tmp
and non-existing directories from $PATH, and call it early in the
build script.
If . is in PATH, gcc-4.4.4 build breaks:
[ALL ] checking what assembler to use...
/tmp/build/targets/arm-unknown-linux-uclibcgnueabi/build/gcc-core-static/arm-unknown-linux-uclibcgnueabi/bin/as
...
[ALL ] config.status: creating as
i.e. "as" is supposed to be the arm-unknown-linux-uclibcgnueabi cross assembler,
but config.status creates a local "as" script which is calling the
host assembler.

3 Prerequisites and instructions for using ct-ng for building a cross toolchain on FreeBSD as host.
5 0) Tested on FreeBSD 8.0
7 1) Install (at least) the following ports
18 Of course, you should have /usr/local/bin in your PATH.
20 2) run ct-ng's configure with the following tool configuration:
21 ./configure --with-sed=/usr/local/bin/gsed --with-make=/usr/local/bin/gmake \
22 --with-patch=/usr/local/bin/gpatch
23 [...other configure parameters as you like...]
25 3) proceed as described in general documentation
26 but use gmake instead of make
