gcc/4.8: fix C++ exceptions and pthread_exit()

Browse Source 
Following the introduction of the support for the musl C library, the
support of C++ exceptions or features like pthread_exit() got broken
even with other libraries such as glibc. This was reported as bug #7028.

The problem was caused by the gcc patch needed to add support for
musl, which modified the libgcc/unwind-dw2-fde-dip.c logic to decide
whether USE_PT_GNU_EH_FRAME should be enabled or not. It completely
removed the existing logic, replacing it by a single logic based on
the definition of TARGET_DL_ITERATE_PHDR. However, this constant gets
defined by the configure script only for Solaris, or Linux Musl
platforms. For glibc/uClibc, the configure script does not define it,
and therefore USE_PT_GNU_EH_FRAME is not defined, causing issues with
exception handling.

This patch fixes that by restoring all the logic of
libgcc/unwind-dw2-fde-dip.c, and just adding the musl logic as one
more case.

It has been successfully runtime tested using the two code examples
provided in bug #7208, with uClibc, musl and glibc.

@ -13,12 +13,19 @@ https://bitbucket.org/GregorR/musl-cross/src. Compared to the upstream version:
causing build failure. Bug reported upstream at
https://bitbucket.org/GregorR/musl-gcc-patches/issue/4/musl-gcc-patches-break-the-build-on.
* change the USE_PT_GNU_EH_FRAME logic to keep the existing gcc logic
and only add the musl one as an addition, not as a replacement. Not
doing this breaks C++ exception handling with glibc, because
USE_PT_GNU_EH_FRAME doesn't get defined due to the configure script
not testing dl_iterate_phdr() on any system except Solaris.
