Your uclibc should provide a working iconv.

iconv(3) is part of POSIX.1-2001 and if yours doesn't work, it's something you 
need to take up with your vendor.

The configure-time check is to check for the presence of the function, not if 
it works at runtime. You can work around the issue by removing the iconv files 
from your toolchain, so that Qt concludes that you don't have iconv.

No, that's different.

That's about the tools in the tools top-subdirectory. qmake, moc, rcc and uic 
and "bootstrapped" tools and they are in src/tools (well, qmake is in qmake). 
Those are installed always.
