692e2b8bcd aarch64: Add support for GNU indirect functions. 
Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.

9d782e8df0 bfd: Make bfd_cache_max_open depend on actual open file limit. 
The current hard coded limit of open files in bfd/cache.c is 10. This
is pretty low these days. Binaries are often linked against much more
than 10 files (and sometimes against more than 100 shared libraries).
When debugging with GDB some files are opened and closed multiple
times because of this low limit. If possible make the BFD cache file
limit depend on the actual open file limit of the process so more BFD
files can be open at the same time.

    * cache.c (BFD_CACHE_MAX_OPEN): Remove define.
    (max_open_files): New static int initialized to zero.
    (bfd_cache_max_open): New static function to set and return
    max_open_files.

ceae87f3fe Use fputc in place of putc to avoid -Wunused-value warning (AIX). 
Currently, bfd does not compile with -Wunused-value because
the following code:

        val = putc ('\n', f);

gets expanded into some code that triggers a warning:

        warning: value computed is not used [-Wunused-value]

This is because putc is implemented as a macro...

>#define putc(__x, __p)  (((!((__p)->_flag & 0xC000)) && \
>                        ((__p)->_flag = ((__p)->_flag  & 0x3FFF) | 0x8000)),\
>                        (--(__p)->_cnt < 0 ? \
>                        __flsbuf((unsigned char) (__x), (__p)) : \
>                        (int) (*(__p)->_ptr++ = (unsigned char) (__x))))

It's the first part, before the coma operator, which triggers
the unused-value warning.

This patch fixes the issue by simply avoiding the macro and using
fputc instead.

bfd/ChangeLog:

        * bfd.c (_bfd_default_error_handler): Replace use of putc
        by fputc.  Add comment explaining why.
