Buiiding LO6.1.4.2 mixes embeded libicuuc with system libicuuc

[Дилян Палаузов <dpa-libreoffice@xxxxxxxxx>]

Hello Eike,

maybe I have not issued "make clean".  Here doing another try with clean build fails, after calling 

../configure --without-doxygen --with-jdk-home=/opt/jdk --with-ant-home=/opt/ant --without-junit && make

"/src/libreoffice-6.1.4.2/build5/workdir/UnpackedTarball/icu/source/common/unicode/urename.h" contains:

#define ublock_getCode U_ICU_ENTRY_POINT_RENAME(ublock_getCode)

"/src/libreoffice-6.1.4.2/build5/workdir/UnpackedTarball/icu/source/common/unicode/uvernum.h" contains:

#define U_ICU_VERSION_SUFFIX _61
#define U_ICU_ENTRY_POINT_RENAME(x) U_DEF2_ICU_ENTRY_POINT_RENAME(x,U_ICU_VERSION_SUFFIX)

so ublock_getCode() in desktop/source/lib/init.cxx:getFontSubset is renamed to ublock_getCode_61().

On my system I have 2x libicuuc.so:

- in /usr/local/lib, which contains ublock_getCode_60 and
- in /src/libreoffice-6.1.4.2/build5/workdir/UnpackedTarball/icu/source/lib/libicuuc.so containing ublock_getCode_61

Linking libsofficeapp.so is performed by calling

which prefers /usr/local/lib/libicuuc.so over -L$W/UnpackedTarball/icu/source/lib/libicuuc.so and the linker complains:
