nat/linux-ptrace.c: add missing gdb_byte* cast
On noMMU platforms, the following code gets compiled: child_stack = xmalloc (STACK_SIZE * 4); Where child_stack is a gdb_byte*, and xmalloc() returns a void*. While the lack of cast is valid in C, it is not in C++, causing the following build failure: ../nat/linux-ptrace.c: In function 'int linux_fork_to_function(gdb_byte*, int (*)(void*))': ../nat/linux-ptrace.c:273:29: error: invalid conversion from 'void*' to 'gdb_byte* {aka unsigned char*}' [-fpermissive] child_stack = xmalloc (STACK_SIZE * 4); Therefore, this commit adds the appropriate cast. gdb/ChangeLog: * nat/linux-ptrace.c (linux_fork_to_function): Add cast to gdb_byte*.
