Subject: [PATCH] Fix RISC-V 32-bit build of riscv-glibc 2.26

This patch fixes two build errors with the 32-bit version of
glibc-2.26 from the riscv-glibc repository.

A void reference to 'refsym' has been added to dl-runtime.c to avoid
an 'unused variable' error when building with '-Werror'.

Some data types were hard-coded for 64-bit in ldsodefs.h. These have
been modified to allow 32-bit builds.

This patch was provided by Fabrice Bellard as part of his RISC-V
Buildroot development source.
