gcc-6.3: backport fix of check for empty string in ubsan.c

2017-04-08T21:48:06+00:00

Building gcc-cross-initial with GCC7 on the host fails due to the
comparison of a pointer to an integer in ubsan_use_new_style_p, which
is forbidden by ISO C++:

ubsan.c:1474:23: error: ISO C++ forbids comparison between pointer and
integer [-fpermissive]
       || xloc.file == '\0' || xloc.file[0] == '\xff'

Backport the fix from upstream GCC to enable the build with GCC 7

2017-02-23T20:29:16+00:00

[NVD] -- https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-6131

The demangler in GNU Libiberty allows remote attackers to cause a denial
of service (infinite loop, stack overflow, and crash) via a cycle in the
references of remembered mangled types.

	remembered type from the stack.

and it syncs with glibc definitions via __needed* defines
to find which datatypes are expected to be defined on top
of glibc. we need same for musl.
