tools: add option BUILD_ALL_HOST_TOOLS to compile all host tools

Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
While experimenting with the AUTOREMOVE option in search of a way to use
prebuilt host tools in different buildroot, it was discovered that the
md5 generated by find_md5 in depends.mk is not reproducible.
Currently the hash is generated by the path of the file in addition to
the file mod time. Out of confusion, probably, there was an idea that
such command was used on the package build_dir. Reality is that this
command is run on the package files. (Makefile, patches, src)
This is problematic because the package Makefile (for example) change at
each git clone and base the hash on the Makefile mtime doesn't really
reflect if the Makefile actually changes across a buildroot or not.
A better approach is to generate an hash of each file and then generate
an hash on the sort hash list. This way we remove the problem of git
clone setting a wrong mtime while keeping the integrity of checking if a
file changed for the package as any change will result in a different
hash.
Introduce a new kind of find_md5 function, find_md5_reproducible that
apply this new logic and limit it only with AUTOREMOVE option set to
prevent any kind of slowdown due to additional hash generation.

appended to the package official name, and the short name won't match.
Failing a name match, the candidate packages are sorted in alphabetical
order, and a dash will come before any number. So in order to prefer
the original library, the dash should be removed from the alternative

Installation
------------
1. Place OpenWrt initramfs image for the device on a TFTP
in the server's root. This example uses Server IP: 192.168.0.2
2. Connect serial console (115200,8n1) to serial connector
GND (which is right next to the thing with MF289F MIMO-V1.0), RX, TX
(refer to this image: https://ibb.co/31Gngpr).
3. Connect TFTP server to RJ-45 port (WAN/LAN1).
4. Stop in u-Boot (using ESC button) and run u-Boot commands:
5. Please make backup of original partitions, if you think about revert to
stock, specially mtd16 (Web UI) and mtd17 (rootFS).
Use /tmp as temporary storage and do:
6. Login via ssh or serial and remove stock partitions
(default IP 192.168.0.1):
# this can return an error, if ubi was attached before
# or rootfs part was erased before.
ubiattach -m 17
# it could return error if rootfs part was erased before
ubirmvol /dev/ubi0 -N ubi_rootfs
# some devices doesn't have it
ubirmvol /dev/ubi0 -N ubi_rootfs_data
7. download and install image via sysupgrade -n
(either use wget/scp to copy the mf289f's squashfs-sysupgrade.bin
to the device's /tmp directory)
Back to Stock (!!! need original dump taken from initramfs !!!)

1. Place mtd16.bin and mtd17.bin initramfs image

4. rename mtd16.bin to web.img and mtd17.bin to root_uImage_s
5. Stop in u-Boot (using ESC button) and run u-Boot commands:
This will erase RootFS+Web:
nand erase 0x1000000 0x800000
