qtdeclarative somehow requires desktop OpenGL (link error)

I faced an error while rebuilding kwin:

/usr/lib/gcc/armv7-alpine-linux-musleabihf/8.3.0/../../../../armv7-alpine-linux-musleabihf/bin/ld: /usr/lib/libQt5Quick.so.5.12.3: undefined reference to `QOpenGLFunctions_1_0::versionProfile()@Qt_5'
/usr/lib/gcc/armv7-alpine-linux-musleabihf/8.3.0/../../../../armv7-alpine-linux-musleabihf/bin/ld: /usr/lib/libQt5Quick.so.5.12.3: undefined reference to `QOpenGLFunctions_3_2_Core::versionProfile()@Qt_5'

Steps to reproduce:

$ pmbootstrap -y zap -d -hc -p -m -o
$ pmbootstrap chroot -b armv7
...
/ # apk add qt5-qtdeclarative
WARNING: Ignoring /mnt/pmbootstrap-packages/armv7/APKINDEX.tar.gz: No such file or directory

...
(62/63) Installing qt5-qtbase-x11 (9999-r14)
(63/63) Installing qt5-qtdeclarative (5.12.3-r0)

Being in a chroot, perform a test and observe result:

Step 2, also in chroot:

# apk add binutils
# nm --demangle --dynamic --defined-only --extern-only /usr/lib/libQt5Gui.so.5.12.3  |  grep -i qopenglfunctions

003492c8 R typeinfo name for QOpenGLFunctions_ES2
00371158 D vtable for QOpenGLFunctions_ES2

Observe that there are no 3_2 symbols in our qtbase, only _ES2 variants.

Looks like our qtbase is incompatible with alpine's qtdeclarative.
