[gentoo-catalyst] Setting cflags for a single package in spec file

[Garrity, Christopher]

Is there a way to set cflags for just a single package inside the spec
file? I don't need/want to override cflags for all packages, just one.
net-ftp/tftp-hpa-5.1 is causing my netboot2 target to fail because of a
bug related to -O2 and gcc-4.5.3 :(
