Remove ARMv7E-M FPV4-SP-D16 build from rmprofile multilibARM/embedded-6-branch
The new instructions in FPV5-SP-D16 compared to FPv4-SP-D16 are not
generated when building libgcc, newlib of libstdc++ such that libgcc.a,
libc.a and libstdc++.a have the same objdump output for these two
variants. It is therefore a waste of build time to be building a
multilib for ARMv7E-M FPV5-SP-D16 when selecting rmprofile multilib
variant. This patch removes that multilib and map FPv5-SP-D16 to
FPv4-SP-D16.
