[gdb] Fix clang buildbreaker
Building gdb with clang, I run into: ... src/gdb/gdbserver/linux-low.c:6190:41: error: comparison of unsigned \ expression < 0 is always false [-Werror,-Wtautological-compare] if (debug_write ("sigchld_handler\n", sizeof ("sigchld_handler\n") - 1) < 0) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~ ... This regression is introduced by commit a7e559cc08 "gdbserver: Ensure all debug output uses debug functions", which replaces calls to write with result type ssize_t with calls to debug_write with result type size_t. Fix this by making debug_write return ssize_t. Build and reg-tested on x86_64-linux. gdb/gdbserver/ChangeLog: 2019-06-19 Tom de Vries <tdevries@suse.de> * debug.h (debug_write): Change return type to ssize_t. * debug.c (debug_write): Same.
