George Rimar 68980850d7 [ELF] - Mention -fPIC in some error messages.
This is PR32429.

We did not mention -fPIC in error about producing dynamic relocation
in readonly segment before. Patch changes that.

Rui Ueyama 6ea72527e0 Change the error message format for an incompatible relocation.
Previous error message style:

  error: /home/alice/src/bar.c:12: relocation R_X86_64_PLT32 cannot refer to absolute symbol 'answer' defined in /home/alice/src/foo.o

New error message style:

  error: relocation R_X86_64_PLT32 cannot refer to absolute symbol: foo
  >>> defined in /home/alice/src/foo.o
  >>> referenced by bar.c:12 (/home/alice/src/bar.c:12)
  >>>               /home/alice/src/bar.o:(.text+0x1)

Rui Ueyama e8785ba4d7 Change the way how we print out line numbers.
LLD's error messages contain line numbers, function names or section names.
Currently they are formatter as follows.

  foo.c (32): symbol 'foo' not found
  foo.c (function bar): symbol 'foo' not found
  foo.c (.text+0x1234): symbol 'foo' not found

This patch changes them so that they are consistent with Clang's output.

  foo.c:32: symbol 'foo' not found
  foo.c:(function bar): symbol 'foo' not found
  foo.c:(.text+0x1234): symbol 'foo' not found

Petr Hosek 5b4f6c6b28 [ELF] Only print symbol name when it is available
Not only symbols (like sections) have names, in case where we
fail to create relocation against such symbol, we should not
print out an empty string, instead we should print a generic
message.

Petr Hosek 4071b1bac3 [ELF] Improve error reporting for relocations
We should always include symbol name when reporting relocations
error to simplify debugging of these issues. Without symbol names
users have to manually investigate which of the libraries contain
invalid relocations which can be cumbersome when linking multiple
libraries.

George Rimar 3ed2b08dad [ELF] - Inform user that we do not support dynamic relocations against text segment.
It was reported in PR28020, that lld does not link code which
gold do. But in fact that is expected behavior as we do not
support DT_TEXTREL.

This patch changes error message as it can report about relocations against
text segments exclusively, other dynamic relocations errors can 
be handled separately.

Rafael Espindola de17d28a32 Don't produce relative relocs to ro segments.
We were already checking for non relative relocations.

If we ever decide to add support for rw text segments this means we will
have a single spot to add the flag.
