I also build recent versions of R following the documentation, with ICU, 
but have not run into these problems. Normally I use RTools 3.4 but now 
I tested just the build using RTools 3.5 and the linking went fine.

According to the error messages, the linking problems _may_ be due to 
incompatible exception handling in compilers used (e.g. when linking a 
library that has been built by an older version of the compiler than the 
one you are using to link via / build other parts of the application).
