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 Fix building gfortran for ARM.
2 http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01010.html
5 The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
7 This target doesn't really have a 128-bit integer type, however it does use
8 TImode to represent the return value of certain special ABI defined library
9 functions. This results in type_for_size(TImode) being called.
11 Because TImode deosn't correspond to any gfortran integer kind
12 gfc_type_for_size returns NULL and we segfault shortly after.
14 The patch below fixes this by making gfc_type_for_size handle TImode in the
15 same way as the C frontend.
17 Tested on x86_64-linux and arm-linux-gnueabi.
