+Subject: [PATCH] icd_generator.rb: fix build failure against gcc-10
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+libtool: link: gcc -shared  -fPIC -DPIC  .libs/libdummy_icd.o .libs/libdummy_icd_gen.o \
+    -ldl  -g -O2   -Wl,-soname -Wl,libdummycl.so.0 -o .libs/libdummycl.so.0.0.0
+ld: .libs/libdummy_icd_gen.o:/home/slyfox/dev/git/ocl-icd/libdummy_icd_gen.h:226:
+  multiple definition of `master_dispatch'; .libs/libdummy_icd.o:/home/slyfox/dev/git/ocl-icd/libdummy_icd_gen.h:226: first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
