gcc with -nodefaultlibs does not add sanitizers library during linkage
with -static-libasan and similar, fix this, by add them explicitly.
From the gcc(1) about -nodefaultlibs:
Do not use the standard system libraries when linking. Only the
libraries you specify are passed to the linker, and options specifying
linkage of the system libraries, such as -static-libgcc or
-shared-libgcc, are ignored. The standard startup files are used
normally, unless -nostartfiles is used.
Plus checked it manually, w/o -nodefaultlibs everything works without
this explicit linkage.
After this patch UBSAN under gcc compiled successfully.
v2: freebsd and darwin
