[HACKERS] configure does not check for bison or flex

[Eric L]

I am installing postgresql from source on 64 bit Ubuntu 14.04 and when I run 
the ./configure script, it is successful, but when I run make it fails with an 
error:

"ERROR: `flex' is missing on your system.  It is needed to create the file 
`bootscanner.c'.  You can either get flex from a GNU mirror site or download an 
official distribution of PostgreSQL, which contains pre-packaged flex output"
I get this same error for "bison".  I can install it with "sudo apt-get install 
bison" and "sudo apt-get install flex".  However shouldn't the ./configure 
script be checking for these first?
