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).

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.

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.
