Check if symbol is defined when converting mov to lea
We need to check if symbol is defined when converting mov to lea since
SYMBOL_REFERENCES_LOCAL may return true on hidden undefined symbols.
* elf32-i386.c (elf_i386_convert_mov_to_lea): Check if symbol
is defined.
* elf64-x86-64.c (elf_x86_64_convert_mov_to_lea): Likewise.
