sqlite: avoid use of unsupported -Ofast CFLAGS
sqlite3 refuses to be built with -ffast-math (a side effect of -Ofast) when it
falls back to implementing its own isnan() function.
sqlite3.c: In function ‘sqlite3IsNaN’:
sqlite3.c:28554:3: error: #error SQLite will not work correctly with the -ffast-math option of GCC.
To work around this, when -Ofast is used replace with -O3.
