Log message:<br>Unhook loongson from the build.

The last compiler update unfortunately does not work on mips64el, with clang 22<br>built with clang 19 being apparently functional, but clang 22 rebuilt with<br>the previous clang 22 hitting deterministic SIGSEGV on various files.

I don't have the time and energy to try and debug this (which is likely an<br>endianness problem, as octeon appears to run happily with clang 22), especially<br>when it takes 10 days for clang to rebuild itself on these machines; and<br>switching back to gcc 4 won't help much as modern software in ports will<br>require a working C++>=11 compiler to build anyway.

We're saddened by this loss, of course.

But we can offer some consolation by offering a link to Miod's OpenBSD stories collection, which has an extensive library of adventures in OpenBSD code.
