sparc: fix unknown escape sequence warnings
I don't know what exactly the code was going for, but the object code
is the same before/after my change, and in looking at the env strings,
this seems to be OK.
Otherwise gcc warns:
cc1: warning: unknown escape sequence: '\$'
cc1: warning: unknown escape sequence: '\)'
cc1: warning: unknown escape sequence: '\040'
cc1: warning: unknown escape sequence: '\$'
cc1: warning: unknown escape sequence: '\)'
