Since 'make check' fails for me with the flags used by 'configure' and since
you pointed me to a page where they suggest different flags, then I naively
deduced that 'configure' might be using the wrong flag... But if you say 
this
is not relevant then fine. I'm not an expert.

Yes it works:

    hpages at churchill:~> gcc -m32 hello.c
    hpages at churchill:~> file a.out
    a.out:          ELF 32-bit MSB executable SPARC Version 1,
    dynamically linked, not stripped
    hpages at churchill:~> ./a.out
    hi
    hpages at churchill:~> gcc -m64 hello.c
    hpages at churchill:~> file a.out
    a.out:          ELF 64-bit MSB executable SPARCV9 Version 1,
    dynamically linked, not stripped
    hpages at churchill:~> ./a.out
    hi

OK this worked too and "make check" was clearly much faster than
with ".../configure --build=sparc-sun-solaris2.9".
Thanks!
