x86_64 embedded profile; gcc link failure building against uclibc

I'm trying to build a recovery initrd targeted at remote administration.
It will "phone home" using OpenVPN, which in turn requires OpenSSL,
which means this needs to be larger than the typical embedded root.

Thus far, I'm trying to use T2's embedded target; if it's not the most
suitable tool for this purpose, I'd appreciate guidance in that
direction. In any case, this is targeting use on x86_64, and I'm unable
to build the embedded target (using uclibc); GCC has a link failure,
apparently trying to link a 32-bit instance of the compiler against the
local 64-bit uclibc.

How can I prevent this?
