Why did SageMath say this? Was it checking for runtime libffi or headers?
config.log:
## Checking whether SageMath should install SPKG libffi... ##
## ------------------------------------------------------- ##
configure:24887: checking for LIBFFI
configure:24894: $PKG_CONFIG --exists --print-errors "libffi"
configure:24897: $? = 0
configure:24911: $PKG_CONFIG --exists --print-errors "libffi"
configure:24914: $? = 0
configure:25100: result: yes
*configure:25108: will use system package and not install SPKG libffi*
