The previous code add all BBFILE_COLLECTIONS/recipes*/*/*.bbappend to BBFILES,
which causes the parsing very slow when there are many layers, e.g., I have 87
layers:
* Before:
$ rm -fr tmp-glibc/ cache; time bitbake -p
real 0m45.173s
user 0m0.560s
sys 0m0.060s
* After:
$ rm -fr tmp-glibc/ cache; time bitbake -p
real 0m25.542s
user 0m0.572s
sys 0m0.040s
It wasted 20s which wasn't worth (The host has 128 threads, it should cost more
time on less power host), use BBFILES_DYNAMIC can fix the problem.
