    lang/gcc10: Revert "fix build with clang 17"
    
    This reverts commit eb5e0517d2a6e25d43fd03786f526e9043543b47:
    
      lang/gcc10: fix build with clang 17
    
      When building lang/gcc10 with recent clang versions, which default to
      C++17, the following errors are produced:
    
        cfns.gperf:35:18: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
           35 | libc_name::hash (register const char *str, register unsigned int len)
              |                  ^~~~~~~~
        cfns.gperf:35:44: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
           35 | libc_name::hash (register const char *str, register unsigned int len)
              |                                            ^~~~~~~~
        ...many more of these...
    
      Upstream fixed this in
      https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=642dc602f89b2c11d5d833a52f37b04427a27cab,
      so apply it.
    
    I accidentally included a patch for devel/electron25 in this commit.
    That one will be split off and committed separately.

-    c++: Regenerate cp/cfns.h.
-    
-    Current cfns.h includes register-qualified variables and that wouldn't
-    play well when bootstrapping with GCC that uses the C++17 dialect,
-    because 'register' was removed in C++17.  Regenerating it using the
-    command specified in cfns.h luckily cleaned this up.
-    
-            * cfns.h: Regenerated.
