[dpdk-dev] [PATCH] mk: fix static build without crypto

[Olivier Matz <olivier.matz@6wind.com>]

If the experimental CONFIG_RTE_LIBRTE_CRYPTODEV is disabled, build of
any crypto pmds will fail because of the missing dependency.  The commit
94288d645 fixes the issue when compiled with shared libraries but there
is still an issue at link time with static libs:

     LD test
     /usr/bin/ld: cannot find -lrte_pmd_null_crypto
     collect2: error: ld returned 1 exit status

Only add the -l linker flags related to crypto PMDs if CRYPTODEV is
enabled.

Fixes: 94288d645 ("mk: fix build without crypto")
