2015-03-16resolv: fix unaligned tmp buffer corner-caseAlexey Brodkin
On execution of "inet/gethost_r-align" test I noticed failure due to unaligned access (instaed of 4-byte aligned 1-byte aligned address was attempted to be accessed). Further investigation confirmed this nice and helpful test failure. Following commit removed usage of ALIGN_BUFFER_OFFSET on entry to __read_etc_hosts_r(): http://git.uclibc.org/uClibc/commit/?id=f65e66078b9f4d2d7f0fc336dee36e78fc467c0f So indeed if target architecture doesn't allow unaligned access and provided tmp buffer is not word aligned (and we will deal with pointers which means word-sized data units), then CPU will fail during execution. In case of ARC we'll see "Unaligned access" exception like this: --->8--- # potentially unexpected fatal signal 7.

2015-02-16ARC: Conditionalise certain relocations as provided by TLS tools onlyVineet Gupta
uClibc mainline supports NPTL which in turns depends on TLS support in the tools (gcc/binutils), which is yet to be merged in dev branches. However there is some non NPTL code in uClibc, added as part of NPTL effort, which relies on certain relocations only provided by NPTL binutils. As a result building the current upstream even for LT.old breaks. So conditionalize that code on tools, bu tin lack of specific versions, we use NPTL enabling as a sign the tools are equipped to handle those relos.
