    As noted in #22244, new symbols were introduced in the current release cycle, particularly:

    • getrandom@GLIBC_2.25
    • getentropy@GLIBC_2.25

    This PR gets rid of them.

    On master (c93e123dc72bfc1bd2c637fdcd032e570d53a7bd):

    $ objdump -T src/bitcoind src/bitcoin-cli src/bitcoin-tx src/bitcoin-util src/bitcoin-wallet src/test/test_bitcoin src/qt/bitcoin-qt | grep 2.25 | wc -l
5

    With this PR:

    $ objdump -T src/bitcoind src/bitcoin-cli src/bitcoin-tx src/bitcoin-util src/bitcoin-wallet src/test/test_bitcoin src/qt/bitcoin-qt | grep 2.25 | wc -l
