yann@1: There are at least three weird glitches in the Makefile:
yann@1:  - the test operator is a dual-equal sign (==) when it should be a single one (=);
yann@1:  - the exclude options are not accepted as is by GNU tar;
yann@1:  - how on earth could KERNEL_SOURCE possibly be equal to DEVEL_PREFIX ???
yann@1: 
yann@1: We (Cedric DUVAL and I, Yann E. MORIN) are not quite sure why it is that way.
yann@1: We're not quite sure either on how to solve this.
yann@1: 
yann@1: What we need is to built a toolchain; in no way we need to install the linux headers.
yann@1:   ==> systematically exclude them from the [s]tar command.

yann@1: This patch is inspired by the svn repository of uClibc as of 20060209.
