Compile a package from source...

Question

I'm trying to learn how to compile a package from source code.
I choose bfgminer as my example. I know there's already a pre-built package.
# Get bfgminer-3.3.0
wget http://luke.dashjr.org/programs/bitcoin … 3.3.0.tbz2
tar -Jxvf bfgminer-3.3.0.tar.bz2
cd bfgminer-3.3.0
pacman -S uthash    # Required Dependencies
pacman -S lm_sensors
# I want to be able to remove unnecessary modules, so I defined CFLAGS:
CFLAGS="--disable-avalon --disable-opencl --disable-bitfury --disable-littlefury --disable-bitforce --disable-modminer --disable-x6500 --disable-ztex"
./configure
# The package compiles successfully, but It seems to have ignored the CFLAGS.
Configuration Options Summary:
  Enabled..Drivers.....: avalon bigpic bitforce bitfury_gpio cairnsmore erupter icarus littlefury modminer opencl opencl:adl opencl:sensors x6500 ztex
  Disabled.Drivers.....: bfsb cpu metabank proxy
    To enable proxy, install libmicrohttpd 0.9.5+ (getwork) or libevent 2.0.3+ (stratum)
  Enabled..Algorithms..: SHA256d
  Disabled.Algorithms..: scrypt
  Enabled..Options.....: ncursesw5
  Disabled.Options.....:
Compilation............: make (or gmake)
  CFLAGS...............:    -pthread -g -O2 -I/usr/include/libusb-1.0    -pthread -Ilibblkmaker
  LDFLAGS..............:   -pthread -Llibblkmaker/.libs -Wl,-rpath,\$$ORIGIN/libblkmaker/.libs,-zorigin  -lpthread  -ldl -lcurl  -ljansson  -L/usr/lib -lncursesw   -lm -ludev -lusb-1.0   -lsensors -lblkmaker_jansson-0.1 -lblkmaker-0.1
Installation...........: make install && ldconfig #(as root if needed, with 'su' or 'sudo')
  prefix...............: /usr/local
What did I do wrong?

Can it be done after the first login as root and changing the root password?
Easy it may be, but it is also incredibly dangerous. I find it terrifying that people even think of doing this.
I don't know which tutorials you are reading but the Beginners' Guide clearly includes this step as the first one to complete after rebooting into your new system:

You should do the minimum necessary as root. You should only ever perform a task as root if (1) the task cannot be performed with less privileges, (2) you understand exactly what the task is designed to accomplish AND (3) you understand why it needs to be performed with root privileges.
While I admit that most do not go this far, I do not compile code with an account which is even in wheel. That means I don't compile even as my regular user - let alone root.
I guess I have just gotten lucky so far. Thanks for your advise.
