go support in gcc fails to compile while building gcc from source

Hello
    I am compiling gcc 10.4.0 and it works well for c and c++. To get go support, configure was given enable-langugages=c,c++,go and later make -j8 and build fails with below error

ake[3]: Entering directory '/home/<username>/srcs/gcc-10.4.0/x86_64-pc-linux-gnu/libgo'
/bin/bash: line 1: /home/<username>/srcs/gcc-10.4.0/host-x86_64-pc-linux-gnu/gcc/gccgo: No such file or directory

I have masked username in log to hide it. Log still holds same as for compile. I did not investigate much on makefile though setup is quite simple. I am using ubuntu linux 22.0.4 and compiling gcc 10.4.0 source tarball taken from ftp of gcc.gnu.org and using binary installed gcc 10.4.0. Below is configure command before make :

./configure --prefix=/home/<username>/srcs/gcc-10.4.0/install   --with-mpc=/home/<username>/srcs/libs/install     --with-mpfr=/home/<username>/srcs/libs/install     --with-gmp=/home/<username>/srcs/libs/install   --enable-languages=c,c++,go

There is not much issue with most things appear due to first compile without go that c and c++ worked.

Pls give inputs if anything missing that compile is failing for go. Do we need go installed before building go from source?

Regards
Anand

Don't use "./configure".  Run configure in a different, empty,
directory.  See https://gcc.gnu.org/install/configure.html .

Don't use "./configure".  Run configure in a different, empty,
