I just want to send you first the two patches that I'm working
with
to build glibc on riscv64. I didn't of course push either of them
yet. I should also say that I've only built glibc, not fully tested
it yet. Results from testing later.
Since I wrote this on the first submission, the patches have now
received extensive testing, used to build thousands of Fedora/RISC-V
packages.
The first one as discussed adds the symlink from /usr/lib64/lp64d to
/usr/lib64. It's both simple because it doesn't involve any
downstream patching of glibc itself, but it's also a little bit
ugly.
The second one is a pretty uncontroversial change to disable
valgrind. We've discussed valgrind on RISC-V with upstream but as
it's a lot of work to port valgrind to new architectures they
understandably don't want to do anything until it's clear how
popular or otherwise the architecture will be. So we don't expect
valgrind any time soon.
I'd like to push the second one which seems uncontroversial.
The first one works for me ...
Rich.

If _libdir and _lib are the same, the second ln will fail.

True .. although on riscv64 they won't be. I guess I could
change ln -s -> ln -sf?
