The Makefile.lib will call "echo -ne" to append uncompressed kernel size to
bzip2/lzma kernel image. The "echo" here depends on the shell that /bin/sh pointing
to. On Ubuntu system, the /bin/sh is pointing to dash, which does not support
"echo -e" at all. Use /bin/echo instead of shell echo should always be safe.

[PATCH] scripts: use non-builtin echo for '-e'

[Amerigo Wang]

Alek reported that on Ubuntu, where dash is used, 'echo -e'
can't work, so let's use non-builtin echo in this case.
