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.

     7 Attached is a patch to add __attribute__ ((noinline)) to
     8 call_gmon_start.
     9 
    10 Without this patch, the sec script that processed initfini.s removes a
    11 part of inlined call_gmon_start, causing undefined label errors.
    12 
    13 This patch solves the problem by forcing gcc not to inline
    14 call_gmon_start with __attribute__ ((noinline)).
    15 
    16 Tested by building for arm-none-lixux-gnueabi.  OK to apply?
