Details:

Hi, I'm working on keywording libffcall for Gentoo Linux RISC-V. I'm working
on libffcall-2.4, my environment is Gentoo Linux RISC-V with lp64d profile on
a HiFive Unmatched, GCC 11.3.0.
The build.log was from Gentoo's portage system. I've checked that build from
source also has the same output.
When I follow README to build and test from source, make check would always
fail on vacall, as ld complains that it cannot relocate R_RISCV64_HI20 when
making a shared object.
I've done some troubleshooting, it seems that Gentoo Linux has GCC PIC/PIE
enabled by default. I can make it pass all the tests by appending "-no-pie"
flag in makefile, changing %hi/%lo pairs to %pcrel_hi/%pcrel_lo, or adding PIC
support by mimicking arm/armhf change from the 2.1 release.
