Ok. It's running openwrt (also so that may well be the case; however I
copied over [1] the libs [2] from the device to my desktop, so that
should be a step in the right direction.... but presumably I need to
match the cross binutils [3] ld with the uclibc ld one?!?

Also tested with fpc at
ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/mips-linux/
which (perhaps unsurprisingly given the above) shows the same problem.

[1] from my notes
openwrt router mips (big endian) uclibc libuClibc-0.9.33.2
copied
/lib
/usr/lib
(only the root dirs)
