build.log -fno-lto

Attached new logfile without LTO optimizations, which result in a more useful log file.

The linker attempts to search in the wrong directory as far as I can tell.

I just got bit by this as well.  The build fails regardless of LTO/no-lto

Doesn't work with fat LTO either. GCC 9.2 or 8.3 are also a bust

Hello,

I had the same problem with the linker ld.bfd transcode does NOT emerge. The error messages are:

ERROR: option '--enable-lame' failed: cannot link against libmp3lame
libmp3lame can be found in the following packages:
  lame  http://www.mp3dev.org/

ERROR: option '--enable-xvid' failed: cannot link against libxvidcore
libxvidcore can be found in the following packages:
  xvid  http://www.xvid.org/
...


When switching to linker ld.gold with 
    binutils-config --linker ld.gold
before emerge transcode, then transcode compiles

Do not forget to switch back to
    binutils-config --linker ld.bfd
afterwards

Maybe you could try this workaraound.

Thanks for this.
