I have the latest gcc from svn, and with "configure --target=avr
--enable-languages=c":
When building with "make" eventually I get:
gcc -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wno-narrowing

avr.c uses c_addr_space_name to get the names of address spaces for
diagnostics. GCC's build machinery does not arrange for this symbol
to be available when linking lto1. If configured with --disable-lto,
the compiler builds, but lto is unavailable.
This issue is causing trouble for people building the avr toolchain,
and will likely affect other targets as they adopt the use of
c_addr_space_name. Please suggest a fix.
