package/coreutils: fix glibc build with gcc >= 14

Browse Source 
ac_cv_func_strerror_r_char_p is hardcoded to no since commit
74b9bf9945 back in 2005 however strerror_r
only returns an int with musl. With glibc or uclibc, strerror_r returns
a char* or an int depending on _GNU_SOURCE value resulting in the
following build failure with gcc >= 14:

strerror_r.c: In function 'rpl_strerror_r':
strerror_r.c:207:9: error: assignment to 'int' from 'char *' makes integer from pointer without a cast [-Wint-conversion]
  207 |     ret = strerror_r (errnum, buf, buflen);
      |         ^

To fix this build failure, don't hardcode ac_cv_func_strerror_r_char_p
to let coreutils pick the correct value
