I thought that the dietlibc binaries are used for the installation process?
Otherwise, I think that uclibc is a nice compromise between size and
functionality.

gmp fails in configure due to a missing iostream.h. IIRC, this file is part of
libstdc++.
The default configure for gmp is --disable-cxx. However, in gmp.conf this will
be overridden by var_append confopt ' ' "--enable-cxx --enable-mpfr". Maybe
this could be made conditional? But how and where is this done correctly?
Even if --disable-cxx is used, the configure step failes when trying to find
out endianess. I will investigate further ...
I don't think that libstdc++ is used anywhere else. Otherwise, uClibc++ may be
an option for the embedded target.

unionfs needs the headers from e2fsprogs installed in order to compile. They
seem to be missing from the packages list. If there are no strong reasons
against, I would propose to add them to the package list.

I can not reproduce that currently. Maybe I need to redo a clean build.

Yes, I think so, too. I let you know if this problem vanishes as soon as gmp
compiles.
On the other side, strongswan is a package much more suited for routers or
gateways than for an embedded target without a real specification.

dietlibc is present at this stage. I think that mininet requires some library
(most probably a resolver library) the is missing in the target
configuration.
I will keep you posted.

Ever tried for a PPC405 (without FPU) ?
With kind regards
