Patch to handle ehopt0.s testcase

Patch to handle ehopt0.s testcase

[J. Johnston]

I have a port whereby the gas/testsuite/gas/elf/ehopt.s testcase is failing.  It is due to the fact
that the port uses $ as the hex prefix.  In the testcase, there is a subtraction of two labels which
start with $L.  The expression parser tries to read them as hex numbers and fails.  The following
patch allows the parser to treat $L as labels instead of as a hex number.

Ok to commit?
