Got the following error with gcc 11

src/mongo/base/string_data.h:82:68: error: 'size_t strlen(const char*)' reading 1 or more bytes from a region of size 0 [-Werror=stringop-overread]

this issue has been fixed with gcc11.3, we need to update v4 gcc to 11.3. 

A/C: We should not let people build on earlier versions.
