MSVC 2012+: Permit linking to 32-bit, MinGW-built libraries.
Notably, this permits linking to the 32-bit Perl binaries advertised on
perl.org, namely Strawberry Perl and ActivePerl. This has a side effect
of permitting linking to binaries built with obsolete MSVC versions.
By default, MSVC 2012 and later require a "safe exception handler table"
in each binary. MinGW-built, 32-bit DLLs lack the relevant exception
handler metadata, so linking to them failed with error LNK2026. Restore
the semantics of MSVC 2010, which omits the table from a given binary if
some linker input lacks metadata. This has no effect on 64-bit builds
or on MSVC 2010 and earlier. Back-patch to 9.3 (all supported
versions).
