QuickJSR 1.2.0 could not be installed on FreeBSD

[jszhao]

I have tried to install QuickJSR 1.2.0 (the version on CRAN) on a FreeBSD workstation. However, I get the following error:

quickjs/quickjs-libc.c:702:12: error: use of undeclared identifier 'environ'

Additional, there are also two warnings:

Now, there are several packages that depends on QuickJSR, it's important to make it work. Thanks a lot.
