exclude ALL packages from build

[Key-Real]

is it possible to exclude all packages from a build when I do:

make all CPU_TARGET=mipsel OS_TARGET=ps1


or is the only way to edit each fpmake.pp like this:

P.OSes:=AllOSes-[embedded,msdos,win16,go32v2,nativent,macosclassic,palmos,atari,zxspectrum,msxdos,amstradcpc,sinclairql,wasi,human68k];

As a first step it would probably be better to only work with make cycle which will only compile the compiler and the RTL or to build the compiler once and do a make all only inside the rtl directory. Once the RTL works you can try to find out where things break in packages.
