making 7.10.1

I am trying to `make'  ghc-7.10.1  from source by  ghc-7.8.3
on Debian Linux.
I command

  > ./configure --prefix=/home/mechvel/haskell/ghc/7.10.1/inst0
  > make >& make.log

The former command seems successful:   
  #define HAVE_EVENTFD 1 #define CC_SUPPORTS_TLS 1

  configure: exit 0

The latter command reports 

checking whether to build static libraries... yes
checking how to run the C++ preprocessor... /lib/cpp
configure: error: in
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details

And I do not find in  config.log  anything suspicious about  cpp.
config.log  does have several `error' messages, like, say

  conftest.c:9:28: error: ac_nonexistent.h: No such file or directory

But, probably, they are harmless.

Please, how to fix?
