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.

1 From http://svn.exactcode.de/t2/trunk/package/base/glibc32/make-install-lib-all.patch
2 Rule to install all needed libraries, not just the ones installed by install-lib,
3 yet not install programs.
4 Needed because we can't use the main install target, as we can't build programs before
5 we have the final gcc installed; linking fails because libeh.a is not present,
6 and glibc insists on linking programs with that library.
