kbuild: Fix size_append issue for bzip2/lzma kernel
Alek Du [Wed, 19 Aug 2009 09:18:39 +0000 (17:18 +0800)]
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.
