Romain Naour fed95ddffa package/gcc: fix build issue with glibc 2.26
../../../../libsanitizer/sanitizer_common/sanitizer_stoptheworld_linux_libcdep.cc: In function ‘int __sanitizer::TracerThread(void*)’:
../../../../libsanitizer/sanitizer_common/sanitizer_stoptheworld_linux_libcdep.cc:241:22: error: aggregate ‘sigaltstack handler_stack’ has incomplete type and cannot be defined
   struct sigaltstack handler_stack;

../../../../libsanitizer/sanitizer_common/sanitizer_stoptheworld_linux_libcdep.cc: In function ‘int __sanitizer::TracerThread(void*)’:
../../../../libsanitizer/sanitizer_common/sanitizer_stoptheworld_linux_libcdep.cc:276:22: error: aggregate ‘sigaltstack handler_stack’ has incomplete type and cannot be defined
   struct sigaltstack handler_stack;
                      ^~~~~~~~~~~~~

The fix is already included in gcc 7.2 release [1]. We have to backport it to
all older gcc release since it's not included in any stable release yet.
