I can think of two things:

1. You're using a triple that is different from your gcc name:

'-target armv7a-linux-gnueabihf'


'-ccc-gcc-name arm-linux-gnueabihf-gcc'

You should use the target as "arm-linux-gnueabihf".

2. You're not including the GCC headers or libraries.

You need to find where GCC keeps its libraries (normally
/usr/lib/gcc/arm-linux-gnueabihf) and headers (if necessary).

In your case, just adding -L"where your gcc libs are" should be enough.
