You can look to CFLAGS variable in your Makefile:
$ grep -r -e '^CFLAGS.*=' */Makefile
common/Makefile:CFLAGS = -g -O2 -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing 
Docs/Makefile:CFLAGS = -g -O2 -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing
...

As you see -O2 and -Wall parameters are set.
To change CFLAGS run:
$ CFLAGS="-g -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing" ./configure
$ grep -r -e '^CFLAGS.*=' */Makefile
common/Makefile:CFLAGS = -g -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing 
Docs/Makefile:CFLAGS = -g -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing -Wall -Wno-pointer-sign -fvisibility=hidden -fno-strict-aliasing
...

The options are doubled, but this isn't a problem.
