Well done for spotting the typo in python36.mk ...

Shouldn't line 130 of mk/sysdep/python.mk be:
+ else ifeq (ArchLinux,${OPSYS})

Otherwise, this means that there is an inconsistency with the file name
mk/platform/ArchLinux.mk, which should be named mk/platform/Arch.mk
instead.

Also, lines 123-125 are useless, since this is the default. But I
agree that they might become useful when/if python37 becomes the
default.

About the line 130, I found it with
$ make show-var VARNAME=OPSYS
Arch

And if I run opsys.sh:
Arch rolling x86_64

in this file, the test looking for /etc/arch-release is not run, becaus the test with /etc/lsb-release is before, and in /etc/lsb release I have:
LSB_VERSION=1.4
DISTRIB_ID=Arch
DISTRIB_RELEASE=rolling
DISTRIB_DESCRIPTION="Arch Linux"

About the line 123-125, I let you choose :)

The /etc/lsb_release is owned by the community/lsb-release package, which is not mandatory.
If I remove it:
$ sh opsys.sh
ArchLinux 4.18.16-arch1-1 x86_64
$ make show-var VARNAME=OPSYS
ArchLinux

So I suggest this: https://github.com/nim65s/robotpkg/commit/6a522091e4302f6df1fae01019aca7ad93407710

Or this one: https://github.com/nim65s/robotpkg/commit/b37c0b58b14cb8a09ee3230a6307b3e65f7d3850
This way opsys.sh gives the same result, whether the package lsb_release is installed or not
