Mark Corbin aee39cbf27 arch/riscv: set the default float ABI based on ISA extensions
This patch sets the default floating point ABI based on the ISA
extensions that have been selected rather than defaulting to soft
float.

For 64-bit:

ISA 'D' selects  lp64d
ISA 'F' selects  lp64f
Otherwise select lp64

For 32-bit:

ISA 'D' selects  ilp32d
ISA 'F' selects  ilp32f
Otherwise select ilp32

This change was proposed by Palmer Dabbelt at SiFive.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
