[ofa-general] [PATCH] opensm/configure.in: make lex/yacc presence mandatory

[Yevgeny Kliteynik]

Hi Sasha,

When configure checks for Lex & Yacc, it uses AC_PROG_YACC & AC_PROG_LEX
macros, which only issue a warning message if a program wasn't found.
Make lex/yacc presence mandatory for configure completion.

Please apply to ofed_1_3 and master.
