Hm, Alpine doesn't have /usr/lib64 and /lib64. Alpine only uses /lib and
/usr/lib. However, it seems that gcc/config/riscv/t-linux assumes that the
lib64/lib32 directory is present:
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/riscv/t-linux;h=216d2776a183d13ade76642b73b9bf04b0c4694e;hb=HEAD
this is contrary to configuration files for other architectures which
explicitly check if the system has lib32/lib64, for example, compare this to
the configuration file for x86_64:
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/i386/t-linux64;h=d288b0935220cc44998da1994a13aa2902db9509;hb=HEAD#l19

Might this be the root cause of this issue?
