Qt Creator cannot be built on 32-bit platforms

On both 32-bit Intel (x86) and 32-bit PowerPC (ppc), the following error occurs while attempting to build the "clangformat" plugin for Qt Creator 4.8.2:

make: *** [Makefile:529: .obj/debug-shared/clangformatconfigwidget.o] Error 1

The phrase "fno" does not appear in any other build file other than the Makefile in the clangformat directory. Both architectures use "-fno-omit-frame-pointer" to aide in producing usable backtraces for debug builds.

PPC:

1. Command: /usr/bin/qmake o Makefile clangformat.pro 'QMAKE_CFLAGS += -O2 -ggdb -mcpu=G3 -fno-omit-frame-pointer -mfpu=dp_full -g' 'QMAKE_CXXFLAGS += -O2 -ggdb -mcpu=G3 -fno-omit-frame-pointer -mfpu=dp_full -g' 'QMAKE_LFLAGS += -Wl,-as-needed' 'QMAKE_LIBS += -lexecinfo'

x86:

1. Command: /usr/bin/qmake o Makefile clangformat.pro 'QMAKE_CFLAGS += -O2 -ggdb -march=pentium-mmx -mtune=pentium-m -fno-omit-frame-pointer -g' 'QMAKE_CXXFLAGS += -O2 -ggdb -march=pentium-mmx -mtune=pentium-m -fno-omit-frame-pointer -g' 'QMAKE_LFLAGS += -Wl,-as-needed' 'QMAKE_LIBS += -lexecinfo'
