package/rustc: RUSTC_TARGET_NAME is needed to build host-rust
As reported on bugzilla [1], the host-rust package fail when
the target architecture or the target libc is not supported.
The error is the following:
failed to parse TOML configuration 'config.toml': expected a table key, found a right bracket at line 15
In such case BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS is
not set thus RUSTC_TARGET_NAME is also not set [2].
But RUSTC_TARGET_NAME is needed to generate the file config.toml [3]
Add BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS in the host-rust
dependency.
The commit [4] that allowed to select host-rust when the target
architecture or the target libc is not supported, should have
allowed to select only host-rustc-bin.
Fixes:
Bug #12691
