commit 8570713a2fa6f01cd68e7d8f6dc232df813720b4

Bug 34386: Fix up clang compilation on Linux
We can't build the crt in the compiler-rt project on Linux anymore and
work around it by disabling that part. This is likely yet another sign
of Debian Wheezy showing its age.
Apart from that, we should use our own binutils and not whatever Wheezy
is providing.

-Subject: [PATCH] [llvm-objcopy] [COFF] Fix handling of aux symbols for big
- objects
-
-The aux symbols were stored in an opaque std::vector<uint8_t>,
-with contents interpreted according to the rest of the symbol.
-
-All aux symbol types but one fit in 18 bytes (sizeof(coff_symbol16)),
-and if written to a bigobj, two extra padding bytes are written (as
-sizeof(coff_symbol32) is 20). In the storage agnostic intermediate
-representation, store the aux symbols as a series of coff_symbol16
-sized opaque blobs. (In practice, all such aux symbols only consist
-of one aux symbol, so this is more flexible than what reality needs.)
-
-The special case is the file aux symbols, which are written in
-potentially more than one aux symbol slot, without any padding,
-as one single long string. This can't be stored in the same opaque
-vector of fixed sized aux symbol entries. The file aux symbols will
-occupy a different number of aux symbol slots depending on the type
-of output object file. As nothing in the intermediate process needs
-to have accurate raw symbol indices, updating that is moved into the
-writer class.

-Subject: [PATCH] [llvm-objcopy] Return Error from Buffer::allocate(),
- [ELF]Writer::finalize(), and [ELF]Writer::commit()
-
-Summary:
-This patch changes a few methods to return Error instead of manually calling error/reportError to abort. This will make it easier to extract into a library.
-
-Note that error() takes just a string (this patch also adds an overload that takes an Error), while reportError() takes string + [error/code]. To help unify things, use FileError to associate a given filename with an error. Note that this takes some special care (for now), e.g. calling reportError(FileName, <something that could be FileError>) will duplicate the filename. The goal is to eventually remove reportError() and have every error associated with a file to be a FileError, and just one error handling block at the tool level.
-
-This change was suggested in D56806. I took it a little further than suggested, but completely fixing llvm-objcopy will take a couple more patches. If this approach looks good, I'll commit this and apply similar patche(s) for the rest.
-
-This change is NFC in terms of non-error related code, although the error message changes in one context.
