include LAPCK, compile with -ggdb, tested for str2str, .gitignore

Hi tyler123durden,

I just started successfully a forward to my ntripcaster
str2str -in serial://ttyAMA0:9600#ubx -out ntrips://:foobar@87.106.90.85:2101/WIRTSGIRG -t 5

which means that the raw data from my cheap NL507ETTL should be accessible in the internet :-)

This also means that your fix for the sigfault issue works for this case as well.
And I think I got a basic grasp of git, plus some working git tools (graphically and console) on my raspberry building setup. I will add a wiki page on that soon.

Would you mind to pull my branch now?

changes I made:
* fix includes for LAPACK , this will solve this issue:
https://github.com/tyler123durden/rtklib/issues?sort=comments&state=open
* add -ggdb to all makefile compiler options
* added .gitignore to keep .o and binaries out of the repo

please have a look at str2str makefile again.
This one is merged manually. I hope I did not screw any of your fixes.

It starts to be funny work this way :-)

Yours 
Wolfgang
