toolchain.eclass: allow CTARGET to contain '.'

Browse Source 
On CTARGET="hppa2.0-unknown-linux-gnu" the following code
    local VAR="CFLAGS_"${CTARGET//-/_}
    CXXFLAGS=${!VAR}
produces incorrect substitution:
    CFLAGS_hppa2.0_unknown_linux_gnu
which caused 'crossdev hppa2.0-unknown-linux-gnu' to fail.

The change adds '.' mangling as well.
