i386: Avoid rely on linker optimization to avoid relocation
lld does not implement all the linker optimization to avoid the GOT relocation as done by binutils (bfd/elf32-i386.c:elf_i386_convert_load_reloc). The current 'movl main@GOT(%ebx), %eax' will then create a GOT relocation when building with lld, which make static-pie status to not being able to start the provided main function. The change uses a __wrap_main local symbol, which in turn calls main (similar as used by aarch64 and s390x). Checked on i686-linux-gnu with binutils and lld.
