While building gcc , I followed the OS Specific Toolchain wiki, in the exact same way,
still on this command: make all-gcc all-target-libgcc: it shows the following error:

checking whether ln -s works... yes

vipul@vipulpc:~/src/build-gcc$ make all-gcc all-target-libgcc

So assuming you properly edited the required files, did you also run autoconf/automake/autoreconf where needed?

yes i have properly did all things including the autoconf/make/ but i encountered the autoreconf part.
