You're missing -lodbc here. Presumably that should have come from
your backtick command, which obviously failed, because it's not the
correct command substitution for this platform.
You either need to find a command substitution that works on ALL of your
platforms, or you need to put something in ./configure which tries
all known commands and selects the one that appears to work, or else you
need to just throw all the commands into one big ugly horrible linker
invocation, something like:
../libtool --tag=CXX --mode=link g++ ... \
$(odbc_config --libs 2>/dev/null) \
$(pkg-config --libs whatever 2>/dev/null) \
...
Or ask an ODBC developers' support channel how you're supposed to do it
on all the platforms you wish to support.

I believe that's caused by the missing -lodbc linker argument. But please
bear in mind that I haven't done serious C development work in many years,
and I've never worked with ODBC in this way before.
