910f6ad1 - [Clang][Driver] Valid `-march` value is not mandatory in AArch64 multilib (#151103)

[Clang][Driver] Valid `-march` value is not mandatory in AArch64 multilib (#151103) If a user passed an invalid value to `-march`, an assertion failure happened in the AArch64 multilib logic. But an invalid `-march` value is an expected case that should be handled via error messages. This patch removes the requirement that the `-march` value must be valid.
