Yes I saw your answer and understood what you were talking about.  
Again, the "-march=armv4t -msoft-float" options are passed to every 
package Buildroot builds since it's an option I enable in the Buildroot 
config file.  The problem may lie in how it passes them to Xenomai 
specifically.  For a fact, I can assure you they weren't passed to the 
right of the ./configure script as you suggested since I double checked 
the config.log for the Xenomai build.   Why the "Illegal Instruction" 
message wasn't showing up I don't know but it's not something that 
popped up to me before for not passing the flags, at least not in the 
smdk2440 target.

Facts:
1- Buildroot doesn't build correctly the Xenomai package ( test suite 
fails to launch )
2- When passing the flags in Buildroot manually ( for now ) to the 
Xenomai package the test suite runs normally
3- The solution is either fixing the parameter passing scheme on Xenomai 
or how Buildroot passes the parameters ( I go with this last one ).
