To solve the issue, you need to install the `arm-linux-gnu-gcc` compiler. You can do this by following the steps below:

1. Check if the `arm-linux-gnu-gcc` compiler is already installed on your system by running the following command:

   which arm-linux-gnu-gcc

If the command returns a path, then the compiler is already installed. Otherwise, you need to install it.

2. Install the `arm-linux-gnueabihf-gcc` package by running the following command:

   sudo apt-get install gcc-arm-linux-gnueabihf

This will install the `arm-linux-gnueabihf-gcc` compiler on your system.

3. After installing the compiler, make sure that it is in the system path by running the following command:

   export PATH=$PATH:/usr/bin/arm-linux-gnueabihf

This will add the `arm-linux-gnueabihf-gcc` compiler to the system path.

4. Finally, try to recompile the OpenSSL library again using the `make` command:

   make depend && make _all

This should compile the OpenSSL library without any errors.
