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 -= BEGIN original header =-
     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
     9 can punt it.
