[RFC] remove -W from build process

[RFC] remove -W from build process

[Sebastian Andrzej Siewior]

I didn't really figured what exactly goes wrong but if I compile with
CFLAGS unset then the compile process goes like this:
| gcc -O2 -Werror -Wall -Iinclude -Isrc -I../../include src/ubiupdatevol.c -c -o ubiupdatevol.o

Once I set the enviroment CFLAGS to "-g -O2" I also get
"-Wall -Wall -Wwrite-strings -W":
| gcc -g -O2 -Wall -Wall -Wwrite-strings -W -Werror -Wall -Iinclude -Isrc -I../../include src/ubiupdatevol.c -c -o ubiupdatevol.o
|cc1: warnings being treated as errors
|src/ubiupdatevol.c: In function 'truncate_volume':
|src/ubiupdatevol.c:179: error: comparison between signed and unsigned
|src/ubiupdatevol.c:183: error: comparison between signed and unsigned
....

and it aborts. I tried to cleanup the signed and unsigned thing but it is
a long a way. So I guess it may be the best to just disable -Wextra for
now.

Would it be possible to use autotools for a clean build environment?

It won't fix compile error, right. I thing it could be easier the handle 
CFLAGS, cross builds, install, build dir, rebuilds, ...
Alternatively one could clean up the current make scripts but I thing it 
would be easier to handle this with auto tools.

ive already posted a patch to cleanup the build system and it should
address every issue you highlighted here ...

Cool. I thing you refer to "unify all common build system parts". It looks 
promising and smaller than my attempt.
