The log shows an x86_64 build, not a universal build.

Relevant messages in the log appear to be:

../Genymobile-scrcpy-bdf5fc3/app/src/cli.c:913:5: warning: implicit declaration of function 'static_assert' is invalid in C99 [-Wimplicit-function-declaration]
    static_assert(SC_WINDOW_POSITION_UNDEFINED == -0x8000, "unexpected value");
    ^

../Genymobile-scrcpy-bdf5fc3/app/src/clock.h:11:15: error: expected parameter declarator
static_assert(!(SC_CLOCK_RANGE & 1), "SC_CLOCK_RANGE must be even");
              ^

My understanding is that static_assert is supposed to be available in C11, which this port is using, so these messages are confusing to me. Perhaps some header needs to be included for static_assert to be available.

Although the build log attached here shows the build failure with scrcpy 1.20, which is out of date, the automated build system saw the same problem with 1.21:

Looks like this has been solved in the latest Portfile update, which uses legacysupport to add static_assert and clock_gettime on older OS X versions.
