Use dlsym to check if libdl is needed for plugin · 520a02b6

config/plugins.m4 has

 if test "$plugins" = "yes"; then
    AC_SEARCH_LIBS([dlopen], [dl])
  fi

Plugin uses dlsym, but libasan.so only intercepts dlopen, not dlsym:

[hjl@gnu-tools-1 binutils-text]$ nm -D /lib64/libasan.so.4| grep " dl"
0000000000038580 W dlclose
                 U dl_iterate_phdr
000000000004dc50 W dlopen
                 U dlsym
                 U dlvsym
[hjl@gnu-tools-1 binutils-text]$

Testing dlopen for libdl leads to false negative when -fsanitize=address
is used.  It results in link failure:

../bfd/.libs/libbfd.a(plugin.o): undefined reference to symbol 'dlsym@@GLIBC_2.16'

dlsym should be used to check if libdl is needed for plugin.

	PR gas/22318
	* plugins.m4 (AC_PLUGINS): Use dlsym to check if libdl is needed.

[PR c++/84979] reject auto in explicit tmpl args for tmpl-fn · 44780b91

With concepts, we accept auto in explicit template arguments, but we

template functions or variables is not allowed.  So, reject it, at
parse time if possible, at specialization time otherwise.
