bzip2/lzma: don't stop search at first unconfigured compression
Alain Knaff [Thu, 19 Feb 2009 21:36:55 +0000 (13:36 -0800)]
Impact: Bugfix, avoids kernels which build but panic on boot

Fix a bug in decompress.c : only scanned until the first
non-configured compressor (with disastrous result especially if that
was gzip.)
