Post the output of

The ldconfig cache is used only by the runtime linker and is not used when you
build a program or library, e.g. not used by /usr/bin/ld.

From the ldconfig output it looks like you are building it on an 64bit ARM
platform (AArch64). What device do you use and which Linux distribution?
