Fix build of older Glibc using GCC >=10
Issue #1535
GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30.
This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10.
This change also adds additional cflags for the target GLibc to disable
new GCC11 checks that lead to compilation errors.
