=E2=80=9Cavr-gcc=E2=80=9D?=20

I have installed the package "avr-toolchain". The program "avr-gcc" is in m=
y profile but I think it was not from the package avr-gcc.

$ ls -l /home/dannym/.guix-profile/bin/avr-gcc
lrwxrwxrwx 143 root guixbuild 69  1. Jan 1970  /home/dannym/.guix-profile/b=
in/avr-gcc -> /gnu/store/lhy6jlpwf92yknmfai3675lmr8bhc4jf-avr-gcc-5.3.0/bin=
/avr-gcc
$ guix package -r avr-gcc
nothing to be done
$ ls -l /home/dannym/.guix-profile/bin/avr-gcc

in/avr-gcc -> /gnu/store/lhy6jlpwf92yknmfai3675lmr8bhc4jf-avr-gcc-5.3.0/bin=
/avr-gcc

I've read through the mailing list but even the "-D__x86_64__" hack doesn't=
 work anymore. Hmm...

> Should application setup for individual applications also be added to the=
 manual?

In general yes - but I think avr-gcc is special in that it really doesn't n=
eed host system stuff at all. There should be no configuration necessary. (=
It is necessary, but it shouldn't be)

Also, I manually added avr/include and avr/lib as a workaround. This mostly=
 works. However, when linking I get:
...
avr-ld: cannot find crtatmega32u4.o: No such file or directory
avr-ld: cannot find -latmega32u4

And indeed this crt doesn't exist at all.
