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 This patch sets the page size to a default 12, that is a 4KiB block size.
2 Testing for the correct block-size is impossible when cross-compiling.
4 It was build up by Yann E. MORIN <yann.morin.1998@anciens.enib.fr> from some
5 bits gathered from buildroot, which is LGPL v2.1
