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.

4 older verisons of glibc would build dl-sysdep as shared-only and dl-support as
5 static-only. alpha hooks in a cache variable via dl-auxv.h. newer versions of
6 glibc build dl-sysdep as both shared and static which means we now have symbol
7 duplication for static builds with dl-sysdep and dl-support. since dl-sysdep
8 is both shared/static, there is no point in hooking dl-support anymore, so we
