it should be defined as an absolute symbol with the given value.

daa88f2f06 [ELF] Handle '[]' in glob patterns 
Previously, mold crashes due to an invalid regex pattern exception
when `[...]` is given as a version script pattern.

43fa021d48 [ELF] Do not place non-exported symbols into .gnu.hash 
Previously, mold put all global symbols into .gnu.hash. Although I
believe it was not an error, it bloated the size of .gnu.hash because
.gnu.hash needs only exported symbols.

907f713e51 [ELF] Remove NEEDS_DYNSYM flag from symbol 
I wanted to make sure that a symbol X is in .dynsym if and only if
(X.is_imported || X.is_exported).

a5029d19a8 [ELF] Automatically fall back to ld.bfd or ld.lld if LTO is in use 
This is very hacky but highly practical, so I couldn't resist to not
implement this. We should support LTO natively in the future. In the
meantime, this feature should work as a poor-man's replacement.
