That suggests something is wrong with your libvirt library.
It should include physmem_total.  That's why it works for me:

    $ rm info1.o && make info1
    gcc -DHAVE_CONFIG_H -I. -I../.. -I../../include -I../../include \
    -I./include -g -O2 -MT info1.o -MD -MP -MF .deps/info1.Tpo -c -o \
    info1.o info1.c
    mv -f .deps/info1.Tpo .deps/info1.Po
    /bin/sh ../../libtool --tag=CC --mode=link gcc -g -O2 -o info1 \
    info1.o -Wall -Wformat -Wformat-security -Wmissing-prototypes \
    -Wnested-externs -Wpointer-arith -Wextra -Wshadow -Wcast-align \
    -Wwrite-strings -Waggregate-return -Wstrict-prototypes -Winline \
    -Wredundant-decls -Wno-sign-compare -Wp,-D_FORTIFY_SOURCE=2 \
    -fexceptions -fasynchronous-unwind-tables ../../src/libvirt.la \
    -lxenstore
    libtool: link: gcc -g -O2 -o .libs/info1 info1.o -Wall -Wformat \
    -Wformat-security -Wmissing-prototypes -Wnested-externs \
    -Wpointer-arith -Wextra -Wshadow -Wcast-align -Wwrite-strings \
    -Waggregate-return -Wstrict-prototypes -Winline -Wredundant-decls \
    -Wno-sign-compare -Wp,-D_FORTIFY_SOURCE=2 -fexceptions \
    -fasynchronous-unwind-tables  ../../src/.libs/libvirt.so -lxml2 \
    -lgnutls -lxenstore -Wl,-rpath -Wl,/usr/local/lib
    libtool: link: creating info1
    $

Please check your library.
Here's what I get:

    $ nm -e ../../src/.libs/libvirt.a|grep physmem
                     U physmem_total
    physmem.o:
    0000000000000060 T physmem_available
    0000000000000000 T physmem_total
    $

And you?

It looks like you're seeing this failure on mingw,
so I think the problem may be a little deeper.
