lex/yacc not configured properly.

lex/yacc not configured properly.

[Srinivasa Chamarthy]

There seems to be a small issue with configure while checking
lex/yacc. Eventhough lex/yacc is available, it fails as the library
name for lex is not what is expected.

library for lex should be "-lfl" instead of "-ll".

+ echo 'Compiling test case lex'
+ do_cc -D_GNU_SOURCE -include config-host.h -o
/tmp/fio-conf-1068-8707-30378.exe /tmp/fio-conf-10872-8707-1500.c -ll
-lnuma -lrt -laio -lz
+ echo gcc -D_GNU_SOURCE -include config-host.h -o
/tmp/fio-conf-1068-8707-30378.exe /tmp/fio-conf-10872-8707-1500.c -ll
-lnuma -lrt -laio -lz
+ gcc -D_GNU_SOURCE -include config-host.h -o
/tmp/fio-conf-1068-8707-30378.exe /tmp/fio-conf-10872-8707-1500.c -ll
-lnuma -lrt -laio -lz
+ return 1
+ arith=no
+ echo 'lex/yacc for arithmetic       no'

The following fixes the issue:

This might fail for solaris. May require some conditional compilation.
