build: Append $(WARNINGFLAGS) to AM_CFLAGS

In src/Makefile.am, remove flex_CFLAGS variable, and append $(WARNINGFLAGS) to AM_CFLAGS. The use of flex_CFLAGS has forced Automake to rename flex's object files (.o) to have a 'flex-' prefix. By preventing the rename, the generated src/Makefile.in can be about 37 kB smaller. Signed-off-by: Kang-Che Sung <[email protected]>
