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 Original patch from Gentoo.
3 -= BEGIN original header =-
4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be
5 8 byte aligned. The dynamic linker's malloc needs to match this so structures
6 become 8 byte aligned to void unaligned accesses.
10 -= END original header =-
