dd04357363 Do not set STT_GNU_IFUNC to symbols .dynsym 
We should not set STT_GNU_IFUNC to symbols in .dynsym because
from the other ELF module's point of view, it doens't matter
whether a symbol is IFUNC or not.

This is needed by Gentoo's sci-mathematics/nauty-2.6.7 package.

f127281d05 Allow empty input files 
mmap(2) fails if you pass 0 as an argument for `length` parameter,
so this case has to be handled as a special case.

This is needed by Gentoo's media-plugins/calf-0.90.3-r1 package.

d3d056d27a Do not register common symbols as lazy symbols 
In other words, a linker shouldn't pull out an object file from an
archive to resolve an existing undefined or a common symbol with a
common symbol.

This is needed by Gentoo's app-arch/dump-0.4.47 package.

c876849144 Allow R_386_GOTPC relocations in non-allocated sections 
This is not logically correct, because PC-relative offsets
make sense only against allocated sections. However,
this is needed by Gentoo's dev-lang/gnat-gpl-2018-r3 package.

9519e4ce20 Change how to handle --unresolved-symbols=ignore 
Previously, we turned unresolved undefined symbols into dynamic
symbols. This patch changed the behavior so that such symbols
are turned into non-dynamic absolute symbols with value zero.

This change is needed by Gentoo's dev-libs/wayland-protocols-1.21
package.

793136a8f0 Give common symbols in archive files higher priority 
If an object file in an static archive contains a common symbol
that can be used to resolve an undefined symbol, mold now pulls
out that object file from the archive. Previously, we ignore such
common symbols.

Object files generated by a Fortran compiler often contain a lot of
common symbols, and this change makes a difference.

Fixes Gentoo's sci-astronomy/wcslib-7.3 package, which contains a
program written in Fortran.
