INSTALL: document shared library pinning for static builds
The libcrypto library uses shared library pinning to prevent its
cleanup handlers from crashing at program termination because of a
premature unloading of the shared library.
However, shared library pinning is enabled also for static builds,
which may lead to surpising behaviour if libcrypto is linked
statically to a shared third-party library, because in this case
the third-party library gets pinned.
This surprising behaviour is caused by the fact that the `no-shared`
configure option does not imply `no-pinshared`. Since this quirk
can't be changed without potentially breaking existing code, we just
document it here and provide a workaround.
