Hello! I have problem building GCC Toolchain
Configure from `~/mips-tc/` with gcc in `~/gcc-6.2.0`:
../gcc-6.2.0/configure --prefix=$HOME/mips-tc --target=mips-elf
--without-headers --with-gnu-ld --with-gnu-as --disable-libssp --disable-nls
--enable-c99 --enable-long-long --disable-libatomic --disable-libgomp
--disable-libquadmath --disable-libmudflap --disable-shared --disable-threads
--disable-multilib --enable-languages=c,c++

make
And in `make` stage after a 3 nights of compilation i am getting this error:

/home/armleo/gcc-bu/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs/libstdc++.a:
