Yes and yes.  I' not a big fan of gnuisms, and occasionally having to go
through config.h's and removing #define malloc rpl_malloc lines seemed a
small price to pay.

Hmm, malloc ... segmentation fault ... you don't think? ... but surely
uClibc would know how to handle its own malloc's return values?

I can, it's even in the list archive ;) along with the information that
switching to 3.81 solves them.  In fact, strace showed that make-3.80 under
some circumstances croaked while trying to mmap all 4GB of virtual memory. 
This was clearly a bug, and now that you mention it, sounds like something
that could happen if one didn't heed the old C commandment "thou shalt not
follow the NULL pointer, for chaos and madness await thee at its end."

What bothers me though is the make-3.81 release note that says they have
introduced some incompatibilites.  I sincerly hope this is meant to be a
joke.  But it was the reason I tried 3.80 first.  After all, I didn't need
new "features", I wanted to compile existing software packages.

But will that work correctly under 2.6?  My current plan is to rebuild
everything under 2.6 and hope for the best.  After all, my shiny new system
boots and the toolchain works (minus pthreads).

Thnks,
Rupert
