How to assign own glibc path to aarch64-elf-gcc

1.
aarch64-elf-gcc need use glibc2.14 while our central version up to glibc-2.12 only
2.
I have downloaded glibc-2.14 in my local directory
3.
There is a limitation in my environment that if I add glibc-2.14 path into LD_LIBRARY_PATH directly, DS-5 eclipse could not open successfully

Therefore, I want to set glibc-2.14 path after I open DS-5 eclipse
4.
I try to assign -I or -L with local directory with ARM DS-5 eclipse to include path
>>>>>>>>>>>>>>>>>>>>>>>>> Command >>>>>>>>>>>>>>>>>>>>>>>>>>
aarch64-elf-gcc -I<local_path>/glibc-build/include -L<local_path>/glibc-build/lib -o "gcc5.axf" ./src/gcc5.o

aarch64-elf-gcc: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by aarch64-elf-gcc)
