When building GCC11 (last tested with 11-20210228) for Windows 32-bit with
MinGW-w64 the build fails with undefined references to LC0/LC1/LC2/LC3.
My build was done using the following configure command:
../configure --prefix=/R/winlibs32_stage/inst_gcc-11-20210228/share/gcc
--build=i686-w64-mingw32 --host=i686-w64-mingw32 --with-pkgversion=MinGW-W64

Note that I was able to build the 32-bit compiler once, but I had to disable
fortran to work around this error. This is the second iteration where I try to
build GCC 11-20210228 with the same version of GCC from the first iteration.
Windows 64-bit builds work fine, so this error is limited to Windows 32-bit.
Any idea what causes this?
