gdb: include <mutex> in dwarf2/read.h
The buildbot pointed out this compilation failure on AlmaLinux, with g++
8.5.0, which is not seen on more recent systems:
CXX gdbtypes.o
In file included from ../../binutils-gdb/gdb/gdbtypes.c:39:
../../binutils-gdb/gdb/dwarf2/read.h:639:8: error: ‘mutex’ in namespace ‘std’ does not name a type
std::mutex dwo_files_lock;
^~~~~
../../binutils-gdb/gdb/dwarf2/read.h:639:3: note: ‘std::mutex’ is defined in header ‘<mutex>’; did you forget to ‘#include <mutex>’?
../../binutils-gdb/gdb/dwarf2/read.h:35:1:
+#include <mutex>
../../binutils-gdb/gdb/dwarf2/read.h:639:3:
std::mutex dwo_files_lock;
^~~
Fix it by including <mutex> in dwarf2/read.h.
