Joseph S. Myers writes:
ELF symbol names are arbitrary 0-terminated sequences of bytes, and the
ELF hash function is defined in the ELF specification to use unsigned
char. Thus uClibc's _dl_elf_hash, using plain char, breaks when char is
signed and symbol names contain bytes with the high bit set, as with GCC's
ucnid-* tests. This patch fixes this problem.
