Subject: build: Restore support for cross-compiling the netsniff-ng toolkit

Ever since we switched to the hand-crafted ./configure script, support
for cross-compiling the netsniff-ng toolkit was basically broken.

Restore the abaility to cross-compile our tools by making ./configure
consider the CROSS_COMPILE and SYSROOT variables.

Example for cross-compiling on arm:

  $ CROSS_COMPILE=arm-linux-gnueabihf- \
    SYSROOT=/usr/arm-linux-gnueabihf \
    ./configure
  $ make

assuming the cross-compiled libraries (and their respective pkg-config
information) are in /usr/arm-linux-gnueabihf.

 And then, build the toolkit like this:

+SYSROOT should be set to the path where your cross-compiled libraries are
+stored, i.e. the path you specify as prefix when configuring the library using
+`./configure --prefix=<prefix>'.
 
 Note that some adaptations might be necessary regarding the CFLAGS, since not
 all might be supported by a different architecture. Probably the most simple
