Yes, indeed.

There's not much we can do here: the uClibc community is so slow at
producing releases that many projects backport a lot of features and
fixes, and therefore from one toolchain to another, the "uClibc 0.9.33"
that you get might be quite different.

While we can certainly require the external toolchains to have a
uClibc configuration that has at least the same features as the
Buildroot uClibc configuration, it seems hard to require those
external toolchains to have in their uClibc a feature that has never
been part of a uClibc release (which is the case of the execvpe being
discussed in this thread).

Best regards,

Thomas
