# 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
|

# 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.
|
|
# 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.
