strace/configure.ac
Dmitry V. Levin c6d15a9b0d Rework ifdefery around print_user_desc 
* configure.ac (AC_CHECK_TYPES): Check for struct user_desc
in <asm/ldt.h>.
* clone.c (print_tls_arg): New function.
(SYS_FUNC(clone)): Use it.
(print_user_desc): Move prototype ...
* defs.h [HAVE_STRUCT_USER_DESC]: ... here.
* ldt.c: Check for HAVE_STRUCT_USER_DESC instead of architectures.
* linux/dummy.h: Likewise.
