Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from "#include_next" (instead of stdlib/stdlib.h in the glibc source directory), and this turns up as a make dependency. Also make a copy of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h. [BZ #21573] * Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add $(common-objpfx)bits/std_abs.h. [$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h): New target. * config.make.in (c++-bits-std_abs-h): New. * configure.ac (find_cxx_header): Use "\,$1," with sed. (CXX_BITS_STD_ABS_H): New. (AC_SUBST(CXX_BITS_STD_ABS_H)): Likewise. * configure: Regenerated.
