When running ./bootstrap-prefix.sh, the script stops when compiling dev-perl/libintl-perl-1.280.0. The same thing happens with all the versions of libintl-perl that I tried.

Seems like it shouldn't use -lintl for your platform. Somehow it thinks it needs it though.
What is the host OS here?
I tried installed this prefix on Mageia 5, updated to the latest version of all packages on the date that I reported this bug.
This section here in configure:
Warning: NAME must be a package name
Warning (mostly harmless): No library found for -liconv
Writing MYMETA.yml and MYMETA.json
Would have emitted the line:
Warning (mostly harmless): No library found for -lintl
If -lintl was not available.
That it detected it in configure, and then failed to find it at compile, smells spicy.
