build: Enable -Wstringop-overflow and -D_FORTIFY_SOURCE=3 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), | ^~~~~~~~~~~~~~~
