   4 Subject: [PATCH 01/44] stdlib: Improve tst-realpath compatibility with source
   5  fortification
   6
   7 On GCC before 11, IPA can make the fortified realpath aware that the
   8 buffer size is not large enough (8 bytes instead of PATH_MAX bytes).
   9 Fix this by using a buffer that is large enough.

  11 (cherry picked from commit 510fc20d73de12c85823d9996faac74666e9c2e7)
