libstdc++: Fix bootstrap failures in src/c++26/debugging.cc
ptrace on Darwin requires <sys/types.h>.
The inline x86 asm doesn't work with the Solaris assembler.
libstdc++-v3/ChangeLog:
* src/c++26/debugging.cc [_GLIBCXX_HAVE_SYS_PTRACE_H]: Include
<sys/types.h>.
(breakpoint) [__i386__ || __x86_64__]: Use "int 0x03" instead of
"int3".
