At least with revision@214413, gcc configured with below options on x86_64.
$ ../gcc/configure --prefix=....../target/
--enable-languages=c,c++,ada,fortran,java,objc,obj-c++,go
Option --print-file-name=liblto_plugin.so doesn't work for installed GCC.
$ ./gcc -print-file-name=liblto_plugin.so
liblto_plugin.so
The file is installed into
./libexec/gcc/x86_64-unknown-linux-gnu/5.0.0/liblto_plugin.so, but gcc's search
dir for libraries are like below (formatted for easy reading's sake).
./gcc --print-search-dirs
