+
+newer versions of gcc generate relocations in the elf_get_dynamic_info func
+which glibc relies on to populate some info structs. those structs are then
+used by ldso to process relocations in itself. glibc requires that there are
+no relocations until that point (*after* elf_get_dynamic_info), so we end up
+crashing during elf_get_dynamic_info because the relocation has not yet been
+processed.
+
+this hack shuffles the code in a way that tricks gcc into not generating the
+relocation. we need to figure out something better for upstream.

+Subject: [PATCH] Makerules: fix MAKEFLAGS assignment for upcoming make-4.4
+ [BZ# 29564]
+
+make-4.4 will add long flags to MAKEFLAGS variable:
+
+ * WARNING: Backward-incompatibility!
+ Previously only simple (one-letter) options were added to the MAKEFLAGS
+ variable that was visible while parsing makefiles. Now, all options
+ are available in MAKEFLAGS.
+
+This causes locale builds to fail when long options are used:
+
+ $ make --shuffle
+ ...
+ make -C localedata install-locales
+ make: invalid shuffle mode: '1662724426r'
+
+The change fixes it by passing eash option via whitespace and dashes.
+That way option is appended to both single-word form and whitespace
+separated form.
+
+While at it fixed --silent mode detection in $(MAKEFLAGS) by filtering
+out --long-options. Otherwise options like --shuffle flag enable silent
+mode unintentionally. $(silent-make) variable consolidates the checks.
+
+Resolves: BZ# 29564

+# CBUILD - machine that will build the binaries
+# If CTARGET != CHOST, it means you want a libc for cross-compiling.

+# CBUILD = CHOST = CTARGET - native build/install
+# CBUILD != (CHOST = CTARGET) - cross-compile a native build
+# (CBUILD = CHOST) != CTARGET - libc for cross-compiler
+# CBUILD != CHOST != CTARGET - cross-compile a libc for a cross-compiler

+# CHOST = CTARGET - install into /
+# CHOST != CTARGET - install into /usr/CTARGET/

+# Note [Disable automatic stripping]
+# Disabling automatic stripping for a few reasons:
+# - portage's attempt to strip breaks non-native binaries at least on
+# arm: bug #697428
+# - portage's attempt to strip libpthread.so.0 breaks gdb thread
+# enumeration: bug #697910. This is quite subtle:
+# * gdb uses glibc's libthread_db-1.0.so to enumerate threads.
+# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols
+# via 'ps_pglobal_lookup' symbol defined in gdb.
+# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all
+# known symbols in 'libpthread.so.0'. Specifically 'nptl_version'
+# (unexported) is used to sanity check compatibility before enabling
+# debugging.
+# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint
+# * normal 'strip' command trims '.symtab'
+# Thus our main goal here is to prevent 'libpthread.so.0' from
+# losing it's '.symtab' entries.
+# - similarly, valgrind requires knowledge about symbols in ld.so:
+# bug #920753
+# As Gentoo's strip does not allow us to pass less aggressive stripping
+# options and does not check the machine target we strip selectively.
+
+# We need a new-enough binutils/gcc to match upstream baseline.
+# Also we need to make sure our binutils/gcc supports TLS,
+# and that gcc already contains the hardened patches.
+# Lastly, let's avoid some openssh nastiness, bug 708224, as
+# convenience to our users.
