# re.mk is used for this and all related packages (rem, restund and baresip).
# It relies on SYSROOT and SYSROOT_ALT being set. SYSROOT is used for finding
# toolchain headers (like pthread.h). SYSROOT_ALT is used for finding headers
# from other packages, like openssl etc.
#
# CFLAGS are picked up from the environment, as well as CPPFLAGS (and LD etc.).
# But LDFLAGS aren't picked up, so they need to be handed over via
# EXTRA_LFLAGS.
#
# LD is changed to TARGET_CC to fix build failures on x86 32bit. Without this
# there's no linking to ssp, which results in undefined references.

# used by 001-extend-ninit-nclose-check.patch
