There were one or two 80186 based machines a long time ago, but
you don't need one.  You can run 80186 code on a 286, 386 or 486
running in real-mode - the 80186 instruction set is is essentially
the sameas that of the 286 with the exception of the  instructions
that relate to protected mode (lmsw, smsw, lgdt, lidt etc ...)
which are not implemented on the 80186.

Any of the standard PC compilers will generate code that will run
on a 186  - if you want to generate optimal code for the 186 you may
have to lie to the compiler and ask it to generate 286 code if
it doesn't have an explicit 186 option. (although I do seem to remember
a bug in the 80186 multiply instruction which might make this unwise ...)
