This enables -Wstringop-overflow compiler warnings:

  'Warn for calls to string manipulation functions such as "memcpy" and
  "strcpy" that are determined to overflow the destination buffer.'

Along with -D_FORTIFY_SOURCE=3 so the errors like the following can be
captured:

In function ‘read’,
    inlined from ‘serial_read_callback’ at emulator/serial.c:90:8:
/usr/include/bits/unistd.h:32:10: error: ‘__read_alias’ specified size between 18446744073709490177 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
   32 |   return __glibc_fortify (read, __nbytes, sizeof (char),
      |          ^~~~~~~~~~~~~~~
