This tries to fix the following link errors on aarch64 when using OpenSSL 3.0.0 alpha 6, compiling it with "no-shared" and -fPIC in CFLAGS, then trying to use the resulting OpenSSL static libraries in the build of elfutils, which embed libcrypto.a into libdebuginfo.so, which hides all symbols (except the libdebuginfod ones) by default: /opt/1A/toolchain/aarch64-v4.0.86/lib/gcc/aarch64-1a-linux-gnu/8.4.1/../../../../aarch64-1a-linux-gnu/bin/ld: /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha1-armv8.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `OPENSSL_armcap_P' which may bind externally can not be used when making a shared object; recompile with -fPIC /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha1-armv8.o): in function `sha1_block_data_order': (.text+0x0): dangerous relocation: unsupported relocation /opt/1A/toolchain/aarch64-v4.0.86/lib/gcc/aarch64-1a-linux-gnu/8.4.1/../../../../aarch64-1a-linux-gnu/bin/ld: /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-chacha-armv8.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `OPENSSL_armcap_P' which may bind externally can not be used when making a shared object; recompile with -fPIC /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-chacha-armv8.o): in function `ChaCha20_ctr32': (.text+0x6c): dangerous relocation: unsupported relocation /opt/1A/toolchain/aarch64-v4.0.86/lib/gcc/aarch64-1a-linux-gnu/8.4.1/../../../../aarch64-1a-linux-gnu/bin/ld: /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha256-armv8.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `OPENSSL_armcap_P' which may bind externally can not be used when making a shared object; recompile with -fPIC /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha256-armv8.o): in function `sha256_block_data_order': (.text+0x0): dangerous relocation: unsupported relocation /opt/1A/toolchain/aarch64-v4.0.86/lib/gcc/aarch64-1a-linux-gnu/8.4.1/../../../../aarch64-1a-linux-gnu/bin/ld: /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha512-armv8.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `OPENSSL_armcap_P' which may bind externally can not be used when making a shared object; recompile with -fPIC /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-sha512-armv8.o): in function `sha512_block_data_order': (.text+0x0): dangerous relocation: unsupported relocation /opt/1A/toolchain/aarch64-v4.0.86/lib/gcc/aarch64-1a-linux-gnu/8.4.1/../../../../aarch64-1a-linux-gnu/bin/ld: /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-poly1305-armv8.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `OPENSSL_armcap_P' which may bind externally can not be used when making a shared object; recompile with -fPIC /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-poly1305-armv8.o): in function `poly1305_init': (.text+0x14): dangerous relocation: unsupported relocation /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-poly1305-armv8.o): in function `poly1305_emit_neon': (.text+0x8e4): relocation truncated to fit: R_AARCH64_CONDBR19 against symbol `poly1305_emit' defined in .text section in /workdir/build/build-pack/build-pack-temporary-static-dependencies/install/lib/libcrypto.a(libcrypto-lib-poly1305-armv8.o) In poly1305-armv8.pl, hide symbols the same way they are hidden in poly1305-x86_64.pl.
