This patch by Charles Wilson went in in 2009 between libtool-2.2.6 and
2.2.8 is causing libtool to use incorrect sys_lib_search_path_spec with
mingw cross compiler:

With libtool-2.2.6 and older, I have this in libtool --config output:

w64-mingw32/lib/
/opt/W64_180676/bin/../../cross_win64/mingw/lib/"
With libtool-2.2.8 and newer, including current git, it is like this:
sys_lib_search_path_spec=3D"/opt/W64_180676/lib/gcc
/opt/W64_180676/x86_64-w64-mingw32/lib64 /opt/cross_win64/mingw/lib64
"
... which is incorrect: /opt/W64_180676/x86_64-w64-mingw32/lib64 does
exist, but it holds only gcc libs, whereas the required libs are under
/opt/W64_180676/x86_64-w64-mingw32/lib, therefore libtool -2.2.8 and
newer cannot build a dll with the following failure:
*** Warning: linker path does not have real file for library -lole32.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libole32 but no candidates were found. (...for file magic test)
*** Warning: linker path does not have real file for library -ldsound.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have

*** Warning: linker path does not have real file for library -lwinmm.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have

*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
.. only because it cannot find the libs. Reverting the above-mentioned
change makes it to work again.
