new v0.14.0 cannot be installed on Alpine Linux

[bastistician]

Alpine Linux uses musl as its standard C library but RTLD_DEEPBIND as used at
https://github.com/mlverse/torch/blob/v0.14.0/inst/include/lantern/lantern.h#L10439-L10442
seems to require __GLIBC__.

Thanks for reporting @bastistician !
Can you check if remotes::install_github("mlverse/torch#1268") works for you?

Yes, that one installs fine.

[dfalbel]

Thanks! I'll make a quick patch release to fix that.
