gnulib: update to 776af40e0
This fixes PR27184, a failure to compile gdb due to
cdefs.h being out of sync with glibc on ppc64le targets
which are compiled with -mabi=ieeelongdouble and glibc
2.32.
Likewise, update usage of _GL_ATTRIBUTE_FORMAT_PRINTF to
_GL_ATTRIBUTE_FORMAT_PRINTF_STANDARD.
Likewise, disable newly added rpl_free gnulib api in
gdbserver support libraries.
Likewise, undefine read/write macros before redefining them
on mingw targets.
Likewise, wrap C++ usage of free with GNULIB_NAMESPACE namespace
as needed.
