Yes, it is.
Compiling: CPPFLAGS + CFLAGS
Linking: CFLAGS + LDFLAGS
GNU autotools handles it in the same way.
See also the gcc man page regarding -flto:
Additionally, the optimization flags used to compile
individual files are not necessarily related to those used at
link time. For instance,
gcc -c -O0 -flto foo.c
gcc -c -O0 -flto bar.c
gcc -o myprog -flto -O3 foo.o bar.o
This produces individual object files with unoptimized
assembler code, but the resulting binary myprog is optimized
at -O3. If, instead, the final binary is generated without
-flto, then myprog is not optimized.
Therefore CFLAGS is required while linking.
