Agreed, will remove the loop and include directly.

I do agree that this would mess up meson debug build. In traditional make
environment we could control file specific cflags but as far as I see I couldnt
find the support for it in meson.
AFAIK meson's default cflags include '-O3' and not '-Ofast'. I will do a quick
benchmark before v2 based on that include the cflag. Also, in case if -Ofast is
necessary I will add a condition to enable it only in case of a normal build.
