glibc-2.42

[Joe Locash]

New minor version.

gcc-15.1.0 will FTBFS because the termio structure is being removed in glibc-2.42. Upstream fix for gcc:

Thanks Joe. I'll hold off with this until glibc-2.42 is actually released, but looking at the patches, I wonder if we can do the same thing by unsetting SANITIZER_GLIBC.

According to ​https://sourceware.org/glibc/wiki/Release/2.42, the new release should be in the next week.

After looking at this a bit, it also looks like we might need to update LLVM for this change too, since libsanitizer is part of llvm as well.

LLVM-20.1.8 already has the fix. I've not checked earlier versions but I'll update LLVM for BLFS soon.

For GCC we just need a simple sed: sed '/struct_termio_sz/d' -i libsanitizer/sanitizer_common/*

We may also want to pick the ​https://sourceware.org/bugzilla/show_bug.cgi?id=33227 fix. We don't enable -D FORTIFY_SOURCE by the book but if a user enables it (s)he may hit a FTBFS due to this issue.
