dante: fix build on some PowerPC platforms
The dante configure script has some logic to remove the -g flag from
CFLAGS, but this logic is flawed and also removed -g in
-mfloat-gprs=double, turning it into the invalid -mfloatprs=double,
causing a build failure.
This commit adds a patch that gets rid of this -g removal logic, since
it is in fact unnecessary.
