MIRROR fails with multiple elements

[ctr49]

kubler.conf describes MIRROR with

# Download location for stage3 and Portage files, use whitespace to set multiple servers
# You may visit https://www.gentoo.org/downloads/mirrors/ and pick a http or ftp url near your physical location
MIRROR='http://distfiles.gentoo.org/'

So multiple mirrors should be allowed.

However, the ARCH_URL construction in core.sh uses the entire string, failing if it contains multiple mirrors.

I think the solution is to treat MIRROR as a set and cast it into an array, using one (the first?) of the MIRROR elements for ARCH_URL (and any future usages of MIRROR).

Doing this, it would also be useful to force or strip a trailing slash in the mirror URL and build ARCH_URL accordingly (it currently breaks when there is no trailing slash).

Thanks for reporting! I added some extra handling that should resolve both issues.

I think this is resolved and can be closed @edannenberg @ctr49
