ChangeLog:
PR lto/42776
* configure.ac (--enable-lto): Refactor handling so libelf tests
are only performed inside then-clause of ACX_ELF_TARGET_IFELSE,
and allow LTO to be explicitly enabled on non-ELF platforms that
are known to support it inside else-clause.
* configure: Regenerate.
gcc/ChangeLog:
PR lto/42776
* configure.ac (gcc_cv_as_section_has_align): Set if installed
binutils supports extended .section directive needed by LTO, or
warn if older binutils found.

(LTO_USE_LIBELF): Likewise.
* gcc/config.gcc (lto_binary_reader): New target-specific configure
variable.

object files in addition to ELF-formatted ones.
(scan_prog_file): Caller updated. Also allow for LTO info marker
symbol to be prefixed or not by an extra underscore.
* config/i386/t-cygming (winnt.o): Also depend on LTO_STREAMER_H.
