lto: Remove link() to fix build with MinGW [PR118238]
I used link() to create cheap copies of Incremental LTO cache contents
to prevent their deletion once linking is finished.
This is unnecessary, since output_files are deleted in our lto-plugin
and not in the linker itself.
Bootstrapped/regtested on x86_64-linux.
lto-wrapper now again builds on MinGW. Though so far I have not setup
MinGW to be able to do full bootstrap.
Ok for trunk?
PR lto/118238
gcc/ChangeLog:
* lto-wrapper.cc (run_gcc): Remove link() copying.
lto-plugin/ChangeLog:
* lto-plugin.c (cleanup_handler):
Keep output_files when using Incremental LTO.
(onload): Detect Incremental LTO.
