build issues w/ system glibc

[Michael Zucchi <notzed@gmail.com>]

Morning,

Just a couple of comments re: building from git.  Well that was the 
intention, but it's turned into a failure to build.

1) bootstrap isn't mentioned anywhere in the README, it just mentions 
configure
2) i know the README is for a web service to reformat, but it's really 
miserable trying to read it from a shell
3) using "guix environment guix" the build fails.

$ make V=1
...
g++ -Wall -std=c++11 -g -O2   -o guix-daemon 
nix/nix-daemon/guix_daemon-nix-daemon.o 
nix/nix-daemon/guix_daemon-guix-daemon.o libstore.a libutil.a

I'm using guix on Slackware-current and that (currently) uses 
glibc-2.30, and when using the platform compiler it links against that 
and not the guix glibc.

I tried installing gcc-toolchain but the same thing happens.  I tried 
-L/gnu/store/<path to glibc> but that doesn't work.
