I just had a look at ifupdown source code, and wordexp() is pretty
central in the code, not sure we can easily replace it with something
else without significantly patching the stuff.

I don't really have a good answer here. Maybe as you suggest disabling
ifupdown entirely for uClibc toolchains? I've also checked
Crosstool-NG, and all its default uClibc configuration files have
wordexp disabled, so both Buildroot pre-built toolchains predating the
wordexp addition and all Crosstool-NG uClibc toolchain would be
affected by the problem.
