btw you can do this without even touching packages themselves, just set
a variable in your mk.conf containing category/pkgdir of all packages
you want to exclude, and do the necessary magick.  e.g.,

  CFLAGS+=3D-ffast-math

  PKG_EXCLUDE_FAST_MATH=3D	databases/postgresql		\
				anothercategory/somethingelse	\
				othercategory/anotherpackage

  _CURPKG=3D			${.CURDIR:H:T}/${.CURDIR:T}

  .if !empty(PKG_EXCLUDE_FAST_MATH:M${_CURPKG})
  CFLAGS:=3D			${CFLAGS:S/-ffast-math//}
  .endif


HTH,
