# 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 disable stripping
# entirely.
