gdbserver: Fix C++ build errors in tracepoint.c
These were introduced by1cda151268
anda13c46966d
. One is a simple missing cast, the other is const usage on global function pointers exported from IPA: in C++, consts are static, and thus won't be exported from the DSO (the build error was because of non-applicable visibility("default")). gdb/gdbserver/ChangeLog: * tracepoint.c (gdb_collect_ptr): Remove const qualifier. (get_raw_reg_ptr): Likewise. (get_trace_state_variable_value_ptr): Likewise. (set_trace_state_variable_value_ptr): Likewise. (initialize_tracepoint): Cast alloc_jump_pad_buffer result to char *.
