`clang -fuse-ld=lld -static-pie -fpie` produced executable
currently crashes and this patch makes it work.
See https://sourceware.org/bugzilla/show_bug.cgi?id=27164
and https://sourceware.org/pipermail/libc-alpha/2021-July/128810.html
While it seems unreasonable to keep csu/libc-start.c ARCH_APPLY_IREL unclear in
static-pie mode and have an unneeded diff -u =(ld.bfd --verbose) =(ld.bfd -pie
--verbose) difference, glibc folks don't want to fix their code.
I feel sad about that but this patch can remove an iffy condition for lld/ELF
as well: `needsInterpSection()`.
// need these symbols, since IRELATIVE relocs are resolved through GOT
// and PLT. For details, see http://www.airs.com/blog/archives/403.
