At least one problem was here:

0
tavasti(at)aladobix:~/work/postgres/postgresql-8.1.4/src/interfaces/libpq$make
ar crs libpq.a `lorder fe-auth.o fe-connect.o fe-exec.o fe-misc.o \
fe-print.o fe-lobj.o fe-protocol2.o fe-protocol3.o pqexpbuffer.o \
pqsignal.o fe-secure.o md5.o ip.o wchar.o encnames.o noblock.o \
pgstrcasecmp.o thread.o crypt.o inet_aton.o getaddrinfo.o open.o \
snprintf.o win32.o libpqrc.o | tsort`
nm: fe-auth.o: File format not recognized ...

Running lorder to find what to link is problem. lorder did not
understand file format, so nothing get's into the library.

This works:

ar crs libpq.a fe-auth.o fe-connect.o fe-exec.o fe-misc.o fe-print.o \
fe-lobj.o fe-protocol2.o fe-protocol3.o pqexpbuffer.o pqsignal.o \
fe-secure.o md5.o ip.o wchar.o encnames.o noblock.o pgstrcasecmp.o \
thread.o crypt.o inet_aton.o getaddrinfo.o open.o snprintf.o win32.o \
libpqrc.o

So I got what I needed, so I didn't start checking whole build system
to make it cross-compiling compatible. Hopefully this helps someone
else in future.
