#174 Compilation error with gcc 6.3, Archlinux

[Eyolf]

During compilation, I get the following error:

Building stockfish-scidb
g++-6.3: error trying to exec 'lto1': execvp: No such file or directory
lto-wrapper: fatal error: g++-6.3 returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
make[2]: *** [Makefile:249: stockfish-scidb] Error 1
make[1]: *** [Makefile:16: all] Error 1
make: *** [Makefile:22: all] Error 2

Previously I got around this by commenting out all the references to engines in the makefile, but after the most recent commit, with the new engine functions, this doesn't work any longer. If I try to open an engine or the engine setup, I get this error:

can't read "Cursors(left_ptr)": no such element in array

I've committed [r1403], this bug should not happen anymore.

Building stockfish-scidb
g++-6.3: error trying to exec 'lto1': execvp: No such file or directory
lto-wrapper: fatal error: g++-6.3 returned 1 exit status

This is a setup problem of the compiler, and not related to Scidb, I cannot help. It's a catstrophe that ArchLinux has bundled gcc7.1, this compiler had a severe problem, only the newer patch levels seems to work. And gcc6.3 has not been installed properly, I don't know how to fix this.
