Merge pull request #1 from GhostLyrics/master

allow executing script, in case @dgruss forgets
update for new sweb-img-util version (fixes problems on windows cross
compilation)
added missing O_BINARY flag (broke windows cross compilation)
Merge branch 'master' of github.com:IAIK/sweb
linux does not know O_BINARY
O_BINARY resulted in strange behaviour, changed to fopen/fread/fwrite
instead
pass -lgcc to compiler instead of linker, compiler knows better where the linker is
and fixed a bug in RegularFile.cpp
"find" in current directory instead of whereever
don't implicitly call "cmake ."

remove this in order to not break cross-compilation on every build of
"mrproper" and "mrsproper"
remove linux specific parameter from "rm" call

(really, it just asks whether you are sure to remove more than 3 files
at once)
