I think you also need to include the supplied object-file for sparcv8 (like
in the default line for linux-sparcv8).
I had to change the line in Configure from
"debian-sparc","gcc:-DB_ENDIAN -DTERMIO -O3 -fomit-frame-pointer -Wall::-D_REENTRANT:-ldl:BN_LLONG RC4_CHAR DES_UNROLL BF_PTR::::::::::dlfcn:linux-shared:-fPIC",
to
"debian-sparc","gcc:-mv8 -DB_ENDIAN -DTERMIO -O3 -fomit-frame-pointer -Wall -DBN_DIV2W::-D_REENTRANT:-ldl:BN_LLONG RC4_CHAR DES_UNROLL BF_PTR:asm/sparcv8.o:::::::::dlfcn:linux-shared:-fPIC",
Without the '-DBN_DIV2W' and 'asm/sparcv8.o' the library was as slow as before
on my box.
