Hi Toad,
Sorry, I wish I could reply quicker, I'm currently busy with some contracted
work, ...
The ARM and uclibc config used to build not too far in the past. uClibC used to
be easier to keep build. Some others are using glibc, too, as some latest X.org
bits started to depend on the latest, greatest glibc features :-(
I agree we should add a soft vs. hard FP option to the config, not only for
ARM, PowerPC, SPARC et al, too. Unfortunately this means we should also test
the option have the desired effect, ...
Patches welcome!
René
