common.mak: Pass -fexceptions to clang and clang++.

This results in generation of .eh_frame sections. These sections
can be discarded during final linking, or included if exception
handling is desired. For exception handling to work, all sources

common.mak: use clang/clang++ to compile C/C++ sources.

Note that -integrated-as is not active by default on OR1K,
so we're still shelling out to binutils to assemble.
It is not yet possible to build everything using -integrated-as.

common.mak: remove RANLIB.
...
`ranlib` is not necessary on any system we can possibly build for,
as it is superseded by `ar s` for the last ten years or so (at least).
Thus, change ar invocations to `ar crs`, also removing a `l` flag
that is ignored by binutils.

common.mak: remove AS.
...
$(AS) was never used: $(assemble) invokes the C compiler instead.
In case of LLVM, this will allow us to consistently use the LLVM
internal assembler for both inline assembly in C and assembly
sources; so, avoid ever invoking binutils as explicitly.

uart.c: rx overflow fix and tx simplification
...
* fixes the clearing of the rx ringbuffer on rx-overflow
* removes tx_level and tx_cts by restricting the ringbuffer
to at least one slot empty
* agnostic of the details of the tx irq: works for uarts that
generate tx interrupts on !tx-full or on tx-empty.
* only rx_produce and tx_consume need to be volatile

bios: add romboot
...
When firmware is small enough, it can be interesting to run code from an embedded blockram memory (faster and not impacted by memory controller activity).
It can also be a fallback option in case boot from flash failed.
To use this, define ROM_BOOT_ADDRESS and initialize the blockram with the firmware data.
