A bit more complicated than that, as uClibc itself was built with the
2.4 headers. You need to rebuild uClibc and the whole devel system.

Grab the source to buildroot. Modify it to use the 2.2 kernel headers.
Type make. Sort out any problems from using the 2.2 headers. We may
have broken something for that case, as I haven't done a test build for
2.2 in at least 9 months.
