auto-import has been turned on by default in the cygwin build since
November, with no ill effects. This patch turns it on by default in
general, but also changes the way auto-import-related
warning/informational messages are issued, depending on whether
auto-import is on by default, or is explicitly enabled (obviously there
are no auto-import-related messages when auto-import is explicitly
disabled...)
Since the tests in /bfd/ against pei386_auto_import are already against
"zero/non-zero", then we can use the same -1 == default (implicitly
enabled), 1 == explicitly enabled, 0 == explicitly disabled formuation
that stdcall_fixup uses.
./bfd/cofflink.c: if (!h && info->pei386_auto_import)
./bfd/linker.c: if (info->pei386_auto_import)
When info->pei386_auto_import = -1 (default) then we continue to issue a
message when auto-importing a variable. If info->pei386_auto_import =
1, then we suppress those informational messages -- the user obviously
knows that she is auto-importing variables, since she explicitly
--enabled them.
I downgraded the "Warning: resolving %s by linking to %s (auto-import)"
message to 'info_msg' on stdout, instead of 'einfo' on stderr.

* ld/ldmain.c (main): initialize link_info.pei386_auto_import
to -1 == implicit enable.
* ld/emultempl/pe.em (gld_${EMULATION_NAME}_before_parse):
initialize link_info.pei386_auto_import to -1 == implicit
enable.
(gld_${EMULATION_NAME}_parse_args): When processing
--enable-auto-import and --disable-auto-import options, use
'1' and '0' instead of 'true' and 'false'.
(pe_find_data_imports): Only issue message about auto-import
when the feature is implicitly enabled. Downgrade message to
informational instead of warning.
