Remove m32r{,le}-*-linux* support from GCC
m32r support never made it to glibc and the support for the Linux kernel was removed with 4.18. It does not remove much but no reason to keep around a port which never worked or one which the support in other projects is gone. OK? Checked to make sure m32r-linux and m32rle-linux were rejected when building. contrib/ChangeLog: * config-list.mk: Remove m32r-linux and m32rle-linux from the list. gcc/ChangeLog: * config.gcc: Add m32r-*-linux* and m32rle-*-linux* to the Unsupported targets list. Remove support for m32r-*-linux* and m32rle-*-linux*. * config/m32r/linux.h: Removed. * config/m32r/t-linux: Removed. libgcc/ChangeLog: * config.host: Remove m32r-*-linux* and m32rle-*-linux*. * config/m32r/libgcc-glibc.ver: Removed. * config/m32r/t-linux: Removed.
