I'm no longer able to compile for attiny85:
klm@pal /tmp ➤ echo '' > test.c
klm@pal /tmp ➤ avr-gcc -mmcu=attiny85 test.c
avr-ld: cannot find crtattiny85.o: No such file or directory
avr-ld: cannot find -lm
avr-ld: cannot find -lc
avr-ld: cannot find -lattiny85
collect2: error: ld returned 1 exit status
I'm currently getting no output for avr-toolchain, which I believe is related:
> ls -l $(guix build avr-toolchain)
total 0
I've been reading
https://issues.guix.gnu.org/39918 and I think it may be causing the problem. It seems that resulted in commit 197c1676d3733f6d8ce30bdc9977ba731b33ec71 (avr-libc going from function to package) which seems to revert part of what's been done in 4d2470b0efb399ad974e2a764db685e952b94323 (avr-libc going from package to function).
I'm hoping would be kind enough to look into this.
