The problem is the linker (presumably /usr/bin/ld) does not
find the math library (likely name is /lib/libm.so.6). You can
add "-v" to the gcc command line to find out what it looks for.

JFTR, building qemu on Debian mips worked for me some days ago,
but the resulting binary was broken (as expected with current CVS).

A plain upstream tarball and the classic
"./configure && make && make install"
should work for that.
