[ELF] - Allow relocation to a weak undefined symbol when -z notext is given. Previously we failed to resolve them when produced executables: "relocation R_X86_64_32 cannot be used against shared object; recompile with -fPIC" Patch fixes it so that we resolve them to 0 for executables. And for -shared case we still should produce the relocation. This finishes fixing PR35720. DIfferential revision: https://reviews.llvm.org/D41551 llvm-svn: 321473

[ELF][test] Change -o %t to -o /dev/null if the output is not needed

[ELF] Remove -Wl,-z,notext hint The hint does not pull its weight: * adding -Wl,-z,notext often won't work (relocation types other than `symbolRel`, e.g. `R_AARCH64_LDST32_ABS_LO12_NC`) * for pure (no assembly) C/C++ projects, the "-fPIC" hint is sufficient
