Since I do not have any 32-bit Cygwin installation, I cannot tell you what the exact value is, but my guess would be "i386-pc-cygwin", or something like that.

Cygwin 32 (no longer supported) was i686-pc-cygwin as are Mingw cross-builds:

$ ls -1 /usr/bin/i*-gcc-[0-9]*
/usr/bin/i686-w64-mingw32-gcc-6.4.0.exe
/usr/bin/i686-w64-mingw32-gcc-7.4.0.exe
