From c00e284dd2baa5ecdb0c9586044399cd7cacce3e Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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.
