Fix non-Linux build failure.

gcc-preinclude.h contains a fix for old Linux systems but it's included
unconditionally on other platforms as well.

I could update the GYP files to exclude it on other platforms but it
seems easier to add a `defined(__linux__)` guard to the header file.

Let this be the last fix.

Fix non-x86 build failure.

The inclusion of gcc-preinclude.h breaks the build on ARM and i386
because of the missing .symver symbol.  Only define it on x86_64.

Closes out mapbox/node-sqlite3#445.
