Yeah, it is the same thing for Fedora/RHEL when we were supporting -m32
for powerpc.
The bi-arch compiler with 32-bit binaries that defaults to -m32, but also
supports -m64 was configured
--build=powerpc64-redhat-linux --target=powerpc64-redhat-linux
--with-cpu=default32
while the bi-arch compiler with 64-bit binaries that defaults to -m64, but
also supports -m32 was simply
--build=powerpc64-redhat-linux
configured.
Similarly for sparc,
--build=sparc64-redhat-linux --target=sparc64-redhat-linux --with-cpu=v7
was the bi-arch compiler with 32-bit binaries that defaults to -m32, but
also supports -m64, while
--build=sparc64-redhat-linux
was the 64-bit binary that defaults to -m64 but also supports -m32.
