It looks like this is because POSIX 2008's getline() is now exported
by default in the newer glibc versions (as of 2.9.90, apparently).

I am forwarding this to the texlive builders list, because the problem
will no doubt pop up soon on more platforms, and I am not the right
person to fix this issue (tangleboot.p is one of the original files
by Knuth).

Interesting fact: metapost does not need tangleboot.p at all, it
is only built because the metapost build process is a subset of
texlive's build process, and turning off that particular bit off
is quite hard. After the failed run of build.sh, you should be able
to go to the 'build' directory and run 'make -k' manually. It
should succeed, with 'mpost' in <build>/texk/web2c afterwards.

Best wishes,
Taco
