Fix checking bignum values that are being inserted into byte sized containers.
* read.c (emit_expr_with_reloc): Add code check a bignum with
nbytes == 1.
* config/rx/rx-parse.y (rx_intop): Accept bignum values for sizes
other than 32-bits.
* testsuite/gas/elf/bignum.s: New test source file.
* testsuite/gas/elf/bignum.d: New test driver file.
* testsuite/gas/elf/elf.exp: Run the new test.
