kernel/linux: symlink custom kernel source dir with '-f'

build fails to symlink to custom kernel dir when the build is not the first time
because of 'ln -s' without '-f' option.

     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.
