Thomas Petazzoni 6ee9bb0fdf 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.

Subject: [PATCH] compiler.m4: do not remove -g flag
A sed expression such as 's/-g//' not only removes the -g
debugging-related flag, but also turns more specific flags such as
-mfloat-gprs=double into -mfloatprs=double, which is no longer a valid
flag.
However, it turns out that removing -g is not necessary: having -g0
after -g negates the -g, and having -ggdb after -g is enough to produce
debugging information for GDB.
