Fix s390 GNU/Linux gdb and gdbserver builds
Now that gdb/gdbserver compile as C++ programs by default, the s390 GNU/Linux build started failing with: In file included from ../../src/gdb/common/common-defs.h:64:0, from ../../src/gdb/defs.h:28, from ../../src/gdb/s390-linux-nat.c:22: ../../src/gdb/s390-linux-nat.c: In function ‘void fetch_regset(regcache*, int, int, int, const regset*)’: ../../src/gdb/../include/libiberty.h:711:38: error: invalid conversion from ‘void*’ to ‘gdb_byte* {aka unsigned char*}’ [-fpermissive] # define alloca(x) __builtin_alloca(x) ^ ../../src/gdb/s390-linux-nat.c:297:19: note: in expansion of macro ‘alloca’ gdb_byte *buf = alloca (regsize); ^ etc. gdb/ChangeLog: 2016-04-21 Pedro Alves <palves@redhat.com> * s390-linux-nat.c (fetch_regset, store_regset, check_regset): Use void * instead of gdb_byte *. gdb/gdbserver/ChangeLog: 2016-04-21 Pedro Alves <palves@redhat.com> * linux-s390-low.c (s390_collect_ptrace_register) (s390_supply_ptrace_register, s390_get_hwcap): Use gdb_byte * and add casts.
