[Buildroot] Building 2.6.19 with Soekris 4801 target

[Eric Malkowski <eric@bvwireless.net>]

This is what I came up with.  The check for uclibc version 0.9.28 AND
kernel >= 2.6.18 I came up with is pretty ugly.  I'm also not certain it
would work right for kernels w/ 4 version numbers like 2.6.15.3 and such.
