Buildfarm failures on urocryon

Hi,

Recently urocryon has been failing with the following errors at [1]:
checking for icu-uc icu-i18n... no
configure: error: ICU library not found
If you have ICU already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-icu to disable ICU support.

configure:8341: checking whether to build with ICU support
configure:8371: result: yes
configure:8378: checking for icu-uc icu-i18n
configure:8440: result: no
configure:8442: error: ICU library not found
If you have ICU already installed, see config.log for details on the
failure.  It is possible the compiler isn't looking in the proper directory.
Use --without-icu to disable ICU support.

Urocryon has been failing for the last 17 days.

I think ICU libraries need to be installed in urocryon to fix this issue.
