When compiling sys-devel/gcc[lto] with >=sys-devel/make-4.4, the gcc build system fails to understand the new --jobserver-auth flag syntax. Instead of serializing the build however it will spawn N lto processes for each N child process, leading to N^2 LTO processes which will very quickly grind to a halt any machine with >8 cores and/or limited memory, and eventually result in an OOM. This may be fixed in gcc master if I am reading correctly, but not backported to 12: https://savannah.gnu.org/bugs/index.php?57242 https://github.com/gcc-mirror/gcc/commit/1270ccda70ca09f7d4fe76b5156dca8992bd77a6 If this is not backported it should IMO be justification for masking >=sys-devel/make-4.4.

The commit you linked seems unrelated, however the one straight after it seems quite related (53e3b2bf16a486c15c20991c6095f7be09012b55). [[ or, more likely, the commit you linked was made to facilitate 53e3b2bf16a486c15c20991c6095f7be09012b55 ]] I'll try reproducing now, I hesitated at first since I first need a copy of 12.2.1_p20221008 (I'm on 12.2.1_p20221203 and 13)
Ok, the latest GCC 12 snapshot indeed omits support for fifo: jobservers. I think it's probably better to backport that than to mask make, though.

Note: - GCC 10 & 11 are pending backports. - No revbump done for 12 yet (this can affect packages building using -flto=jobserver, not just GCC itself, but this isn't very common) as I plan to keyword the next snapshot which is due in 2 days anyway
