Strange www/firefox issue on aarch64

[John Klos <john%ziaspace.com@localhost>]

This is strange... The first time a clean build of www/firefox is 
attempted on 9.99.77 aarch64, it fails with this:


checking MOZ_ICU_CFLAGS... -I/usr/local/include
checking MOZ_ICU_LIBS... -L/usr/local/lib -licui18n -Wl,-R/usr/local/lib 
-licuuc -licudata
checking for nodejs...  1: 0x2005fb050 node::Abort() [/usr/local/bin/node]
 2: 0x2005d2eb4 node::InitializeOncePerProcess(int, char**) 
[/usr/local/bin/node]
 3: 0x2005d2f58 node::Start(int, char**) [/usr/local/bin/node]
no
ERROR: NODEJS must point to node 10.22.1 or newer; found node location: 
/usr/local/bin/node.

    Executing `mach bootstrap --no-system-changes` should
    install a compatible version in ~/.mozbuild on most platforms.
    If you believe this is a bug, <https://mzl.la/2vLbXAv> is a good way
    to file.  More details: <https://bit.ly/2BbyD1E>

*** Error code 1

Stop.
make[1]: stopped in /usr/pkgsrc/www/firefox
*** Error code 1


Simply starting the build again results in success. Ideas, anyone?
