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.

5 The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
6 you have to actually list out the multilibs you want or you will end up with
7 just one when using targets like 'sh4-linux-gnu'.
9 The resulting toolchain can't even build a kernel as the kernel needs to build
10 with the nofpu flag to be sure that no fpu ops are generated.
12 Here we restore the gcc-3.x behavior; the additional overhead of building all
13 of these multilibs by default is negligible.
