commit: http://git.uclibc.org/uClibc/commit/?id=d5e3720ee1186a9640f2614e7d3f4ffbf23a7647
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

Native GDB requires elf_fpregset_t to be defined, even if floating point
registers are absent. In this case we use empty structure. Additionally we
redefined prfpregset_t to use this new type.

And there has been an error: it was defined that user_regs_struct has 20
registers, while it has 40.
