Convenient if you have configured to use mold for a particular project but want
to test a new local build.

open() can fail with transient reasons, such as running out of file descriptor
limit. Previously, this was treated the same as file not being found, which
caused confusing error messages [1].
With this change anything but ENOENT will be treated as a fatal error. This will
also include e.g. permission errors, but if there's something within the search
path that is not accessible, it's likely better to tell the user instead of
silently skipping it.

STT_GNU_IFUNC is significant only for exported symbols. Setting
non-exported symbol type to STT_GNU_IFUNC actually causes an issue
if the symbol is used as a canonical PLT because the runtime would
try to run the canonical PLT as an IFUNC.

Handle .eh_frame in a similar way as mergeable sections.
This seems to be required for GCC CRT compiled with LTO.

When LTO is enabled for CRT it seems symbols like __EH_FRAME_BEGIN__.lto_priv.0
can be created. Treat it as the same as the non-LTO variant.
