package/gcc: add patches to remove crypt()/crypt_r() libsanitizer interceptors

In preparation for the upgrade of glibc to version 2.39, we need to
backport some gcc patches. Indeed glibc 2.39 drops libcrypt, causing a
build failure of libsanitizer (part of gcc) as it has code to
intercept crypt() and crypt_r() calls. This has been fixed in gcc
master, but we need to backport the fix for gcc 11.x, 12.x and 13.x.

gcc 8.x doesn't need to be fixed because (1) its libsanitizer does not
have an interceptor for crypt()/crypt_r() and (2) we only allow gcc
8.x for PowerPC SPE, for which we only support uClibc-ng, so this
issue with crypt/crypt_r going away from glibc is not relevant.

Subject: [PATCH] Remove crypt and crypt_r interceptors
From Florian Weimer's D144073
> On GNU/Linux (glibc), the crypt and crypt_r functions are not part of the main shared object (libc.so.6), but libcrypt (with multiple possible sonames). The sanitizer libraries do not depend on libcrypt, so it can happen that during sanitizer library initialization, no real implementation will be found because the crypt, crypt_r functions are not present in the process image (yet). If its interceptors are called nevertheless, this results in a call through a null pointer when the sanitizer library attempts to forward the call to the real implementation.
>
> Many distributions have already switched to libxcrypt, a library that is separate from glibc and that can be build with sanitizers directly (avoiding the need for interceptors). This patch disables building the interceptor for glibc targets.
Let's remove crypt and crypt_r interceptors (D68431) to fix issues with
newer glibc.
For older glibc, msan will not know that an uninstrumented crypt_r call
initializes `data`, so there is a risk for false positives. However, with some
codebase survey, I think crypt_r uses are very few and the call sites typically
have a `memset(&data, 0, sizeof(data));` anyway.
