d97df66b39 ⚠️ modify handling of makefile's MARCH and MABI variables 
Pre-commit usage: `MARCH=-march=rv32i`, the `-march` should not be here

Post-commit usage: `MARCH=rv32i`, this is more straightforward

Same for `MABI=-mabi=...` -> `MABI=...`

e44cb43819 [sw] no more use of "neorv32_uart_*" legacy wrappers 
all of the software is now using `neorv32_uart0_*` instead of the legacy wrappers `neorv32_uart_*`; however, the legacy wrappers are still implemented

511e37b6b6 [sw] optimized intrinsic libraries 
Intirnsics (pseudo custom instructions) for "Zfinx" and "Zbb" extensions
* now using true inlining
* no more pseudo operations
-> faster execution; closer to the original/native instructions

ce66253b74 [sw/example/floating_point_test] updated Zfinx intrinsic library 
* intrinsics and emulation function now have the same "interface" (arguments and return value)
* added "flush_to_zero" function so arguments get "de-denormalized" before doing actual computations
