Hi from crosstool-ng,

I've had a user report a build error for GCC 13.2.0 with and aarch64 config
with libsanitizer enabled
(https://github.com/crosstool-ng/crosstool-ng/issues/2010).

[ERROR]   
/home/ctng/crosstool-ng/.build/aarch64-unknown-linux-gnu/src/gcc/libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cpp:180:10:
fatal error: crypt.h: No such file or directory
[ALL  ]      180 | #include <crypt.h>
[ALL  ]          |          ^~~~~~~~~
[ALL  ]    compilation terminated.
[ERROR]    make[5]: *** [Makefile:614: sanitizer_platform_limits_posix.lo]
Error 1
[ERROR]    make[5]: *** Waiting for unfinished jobs....

It looks like this may have already been fixed in master by commit d96e14ceb947
("libsanitizer: merge from upstream (87e6e490e79384a5)"). Is that the kind of
thing that might end up in the 13.x branch? Alternatively is there a lower
impact change that might be back-ported?

Thanks,
Chris
