Subject: [PATCH] pkgs/development/libraries/sqlite/default.nix: enable
 amalgamation build

Sqlite has a build mode called "amalgamation" that gathers all 90+ source code
files into a single sqlite3.c file before compiling the library. Building
sqlite this way reportedly gives a 5-10% performance gain because the compiler
can perform more sophisticated optimizations.
