Merge remote branch 'origin/master' into prelink
* origin/master: arm: fix the static link problem for ARM due to undefined __tls_get_addr nios2: Name architecture correctly in endian.h header nptl/mips64: Fix build when using mips64 and ABIs other than o32 mips: avoid segmentation fault when RLD_MAP is 0 libc: fix linker script generation for libubacktrace.so stdio: fix diagnostic message Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
