[screen-devel] [PATCH] fix configure failed while build dir name contains "yes"

[Hongxu Jia]

While build dir name contained "yes", and compiled with
producing debugging information (-g), the configure failed.

The pattern of AC_EGREP_CPP (string "yes") mismatched with
dir name. It caused the test of AC_EGREP_CPP incorrect.

Use YES_IS_DEFINED to replace yes which is not often used
as dir name.

Bug: 52329
(Fix release v.4.6.2 or above)
