Looks good to me, I didn't see an increase in kernel size when selecting
this option on ar71xx (I looked at the size of
"build_dir/target-mips_24kc_musl-1.1.15/linux-ar71xx_generic/linux-4.4.30/vmlinuz")

However, I had to do a "make clean", because selecting
KERNEL_CRYPTO_PCRYPT does not cause all kmod packages to be rebuilt for
the new kernel config:

    Collected errors:
     * satisfy_dependencies_for: Cannot satisfy the following dependencies for  kmod-lib-crc-ccitt:
     *      kernel (= 4.4.30-1-288c1d58c9e4426041f1cf660ee89665) *
     * opkg_install_cmd: Cannot install package kmod-lib-crc-ccitt.
    …
    make[2]: *** [package/install] Error 255
    make[2]: Leaving directory `/home/bjonglez/lede'
    make[1]: *** [/home/bjonglez/lede/staging_dir/target-mips_24kc_musl-1.1.15/stamp/.package_install] Error 2
    make[1]: Leaving directory `/home/bjonglez/lede'
    make: *** [world] Error 2 

Jow, does this have the potential to break the buildbot setup?
