filecaps require the kernel to support security xattrs on the
filesystems used for install (and merge, iirc, not sure if the eclass
works this around — at the time it was written, tmpfs didn't support
xattr; now it does so it does support filecaps), and the
filesystem-based capabilities as well (which might be forced-on right
now but I'm not going to bet on it).

E.g.:

CONFIG_EXT4_FS_XATTR=y
CONFIG_TMPFS_XATTR=y
