Building DYNAMIC_ARCH=1 with only DBUILD_DOUBLE=1 fails for COOPERLAKE target #3910
Description
I'm trying to build a dynamic arch with only double versions (x86_64/Debian bullseye/gcc) using cmake
cmake .. -DBUILD_DOUBLE=1 -DBUILD_SINGLE=0 -DBUILD_COMPLEX=0 -DBUILD_COMPLEX16=0 -DDYNAMIC_ARCH=1 -DDYNAMIC_OLDER=0
fails with

which looks like COPPERLAKE failed. However, building COOPERLAKE directly seems to work without issues
cmake .. -DBUILD_DOUBLE=1 -DBUILD_SINGLE=0 -DBUILD_COMPLEX=0 -DBUILD_COMPLEX16=0 -DDYNAMIC_ARCH=0 -DDYNAMIC_OLDER=0 -DTARGET=COOPERLAKE
Is there any specific reason why dynamic arch would fail with single/complex disabled?
