misc: update ignored files

The place where toolchains were built has moved
from targets/ to .build/

We still ignore the old target/ dir, as users may have
samples that still use that location.

Also, reorder the ignore paterns.

     3 I tried to use crosstool-ng to generate a toolchain for Linux on big
     4 endian arm with recent versions of gcc, glibc, etc... but had a few
     5 problems.

     7 It appears that the gcc patch (for gcc 4.2.x)
     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached
     9 to this mail as 240-arm-bigendian2.patch.
