m32r: fix build failure

The allmodconfig build of m32r is failing with the error:

lib/mpi/mpih-div.o: In function 'mpihelp_divrem':
mpih-div.c:(.text+0x40): undefined reference to 'abort'
mpih-div.c:(.text+0x40): relocation truncated to fit:
R_M32R_26_PCREL_RELA against undefined symbol 'abort'

The function 'abort' was never defined for the m32r architecture.

Create 'abort' as is done in other arch like 'arm' and 'unicore32'.
