This is calling make not gmake, so you have not told the configure
process you will be using gmake. Try (under csh)

env MAKE=gmake ./configure

Alternatively, add

MAKE=gmake

to config.site.

Final alternative: use Sun's make.

but not for Sun's make.

It looks to me as if the configure script will override those settings, as
it has


CPICFLAGS=${CPICFLAGS-${cpicflags}}
FPICFLAGS=${FPICFLAGS-${CPICFLAGS}}
SHLIBLDFLAGS=${SHLIBLDFLAGS-${shlibldflags}}
...
  *solaris*)
    SHLIBLDFLAGS="-G"
    if ${cc_is_gcc}; then
      CPICFLAGS=-fPIC
    else
      CPICFLAGS=-KPIC
    fi
    if ${f77_is_g77}; then
      FPICFLAGS=-fPIC
    else
      FPICFLAGS=-PIC
    fi

It seems likely that it is failing to detect that your g77 (which is
rather old) is actually g77. 

The solution is to run

rm config.cache
env MAKE=gmake ./configure
edit Makeconf to set FPICFLAGS
gmake
