Fix use distro toolchian
The LD fudging broke --enable-distro-toolchain
because Ld
wasn't added to the list of searched for tools.
The Hadrian support broke it as well because it added some strict requirements on $toolsdir
that don't exist when you're using the build in distro toolchain.
This wires through a value USE_INPLACE_MINGW_TOOLCHAIN
that allows us to turn off these Hadrian checks.
Tested Make but someone not tested Hadrian... Still can't get that to work reliably.
Fixes #16780 (closed)
