Thanks for testing Romain ... my fault, I only tested this with the
internal glibc toolchain (on ARM and x86) which I have readily available
and thought it was okay. I will play around with your findings and test out
what works best for uClibc. I am still learning the intricacies of
Buildroot and Cmake (and Git for that matter) but will see what I can find,
otherwise I request the help of the gurus here :-) I researched many other
test frameworks and found this one to be the most feature rich and flexible
for C so worth having in Buildroot I'd say.
